The McDonald's Play Place is going to increase its ball pit size to allow for more fun! The ball pit was originally 10 feet by 12 feet. They have decided to increase each side by the same amount. Express the area of the new pit as a polynomial in simplest form.
Answer:
A = x² + 22x + 120
Step-by-step explanation:
Since the ball pit was originally 10 feet by 12 feet and each side is increased by the same amount which we would call x, the new length of sides are thus 10 + x and 12 + x respectively.
The area of the new pit is thus A = (10 + x)(12 + x), since it is a rectangle.
Expanding the brackets, we have
A = 10 × 12 + 10x + 12x + x²
collecting like terms, we have
A = 120 + 22x + x²
A = x² + 22x + 120
Find the value of x.

Jerry rhombus has a base of 15 inches and a height of 9 inches. Charlene rhombus has a base
Complete Question:
Jerry’s rhombus has a base of 15 inches and a height of 9 inches. Charlene’s rhombus has a base and a height that are 13 the base and height of Jerry’s rhombus. Compare the area of Charlene’s rhombus to the area of Jerry’s rhombus.
Answer:
Charlene's rhombus has a larger area
Step-by-step explanation:
Given
Jerry's
[tex]Base = 15in[/tex]
[tex]Height = 9in[/tex]
Charlene's
[tex]Base = Height = 13in[/tex]
Required
Compare both areas
The area of rhombus is:
[tex]Area = Base * Height[/tex]
For Jerry's
[tex]Area = 15in * 9in[/tex]
[tex]Area = 135in^2[/tex]
Charlene's
[tex]Area = 13in * 13in[/tex]
[tex]Area = 169in^2[/tex]
By comparison: Charlene's rhombus has a larger area by 34in^2

Lucas scored 9 goals in 4 soccer games last season. Approximately how many points did Lucas average per game?
Answer:
Lucas scored approximately 2.25 or 2 1/4 goals per game.
Step-by-step explanation:
To find out just divide 9 to 4. Hope this helps :)
Lucas scored points at an average 2.25 per game.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.
Given:
Lucas scored 9 goals in 4 soccer games last season.
Average per game = total goals / total game.
= 9/4
= 2.25
Therefore, the average is 2.25 per game.

Step-by-step explanation:
What are the square roots of each perimeter of a rectangle?
Answer:
Step-by-step explanation:
The perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x . Therefore, if given an area, all you'd do is take the square root (to get from x2 to x , and then multiply by 4 to find perimeter.
Answer:
The first method
Take a square root, then multiply it by 4.
The defining characteristic of a square is that its length is equal to its width. Take a look below:
Self-created
So, for this particular square, the area is length⋅width, or x⋅x=x2. Now, how can you go from this to perimeter?
Well, the formula for perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x.
Therefore, if given an area, all you'd do is take the square root (to get from x2 to x, and then multiply by 4 to find perimeter.
The second method
s=√A
P=4×s
Explanation:
To find the perimeter of square, you just need to know the length of one side, because in a square all the sides are the same length.
If you know the area, find the square root of it to find the side.
s2=A
∴s=√A
Now you multiply by 4
For example, if the area is 36cm2
A=36
s=√36=6
P=4×6=24

tap A fills a tank in 6 hours tap B fills it in 8 hours and tap C empties it in 10 hours. starting with an empty tank and all the three taps are opened find how long it takes to fill the tank?
Answer:
It will take 5 hours and 5 minutes to fill the tank
Step-by-step explanation:
Here, we want to get the time taken to fill the tap
Let us have the rate per hour
A fills in 6 hours; so the fraction filled in an hour is 1/6
B fills in 8 hours, so the fraction filled in an hour is 1/8
C empties in 10 hours, so the fraction removed per hour is 1/10
So factoring the supply and removal, where removal is on a negative basis
we have it that in an hour, the fraction retained is;
1/6 + 1/8 - 1/10
= (20 + 15 - 12)/120
= 23/120
So this is the fraction retained per hour
The number of hours it will take to have a whole is simply the reciprocal of this fraction
That would simply be 120/23 = 5 5/23
5 hours and 5 minutes

Step-by-step explanation:
A politician claims that a proposal for a new traffic law is broadly supported by both political parties and that a person from either political party is equally likely to support the proposed legislation. He cites two recent polls that said 70% of a random sample of 550 people from his political party supports the law, and 65% of a random sample of 420 people from the other political party supports the law. The 95 percent confidence interval for the difference in population proportions is (–0.010, 0.110). Based on the interval, is the politician’s claim justified?
Answer:
Based on the 95% confidence interval for the difference in population proportion, there is convincing statistical evidence that he is correct
Step-by-step explanation:
The proportion from the sample of people from his party that support the law = 70%
The number the members of the politicians political party that support the law = 550 people
The proportion from the sample of people from the other party that support the law = 65%
The number the members of the politicians political party that support the law = 420 people
The confidence level of the test = 95%
The given confidence interval for the difference in proportion, C.I. = (-0.010, 0.110)
Given that the 95% confidence interval for the difference in population proportion ranges from -0.010, to 0.110, it is 95% certain that 0 is among the likely difference in proportion between the two populations and therefore, there is sufficient statistical evidence to suggest that there is no difference in the proportion of the members of either political that support the proposed new traffic law.

Use the quadratic formula to solve the equation X(-2x – 11) = -3.
Replace m, n, and p with the correct values.
Answer:
I got it correct and this is the right answer:
The roots of the given quadratic equation are (- 11 ± √145)/4. Therefore, m = - 11, n = 145, and p = 4.
What is a quadratic equation?"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0)."
The given quadratic equation is:
x(- 2x - 11) = - 3
⇒ - 2x² - 11x = - 3
⇒ 2x² + 11x = 3
⇒ 2x² + 11x - 3 = 0
⇒ x = [- 11 ± {√(11²) - 4×2×(- 3)}]/(2 × 2)
⇒ x = [- 11 ± {√121 + 24}]/4
⇒ x = (- 11 ± √145)/4
Therefore, for the given quadratic equation, m = - 11, n = 145, and p = 4.

this is standard form (9x10 to the power of -4) to the power of 2
Answer:
9×10 to the power of -8
Step-by-step explanation:
Cause when we add power to the power we multiply them
For example [tex](2^{2} )^2[/tex] , we multiply the power so , 2×2= 4 so [tex](2^{2} )^2[/tex] = [tex]2^{4}[/tex]=16
Same here [tex]((9*10)^{-4} )^2[/tex] we multiply the powers so -4×2=-8
So [tex]((9*10)^{-4} )^2[/tex] =[tex](9*10)^{-8}[/tex] = 2.323×[tex]10^{-16}[/tex]
factor the trinomial 6y^2+19y+15?
Answer:
6y^2+43
Step-by-step explanation:
6y^2+(19+15)
Answer:
(2y+3)(3y+5)
Step-by-step explanation:
6y^2+19y+15
Factor the expression by grouping. First, the expression needs to be rewritten as 6y^2+ay+by+15. To find a and b, set up a system to be solved.
a+b=19
ab=6×15=90
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 90.
1,90
2,45
3,30
5,18
6,15
9,10
Calculate the sum for each pair.
1+90=91
2+45=47
3+30=33
5+18=23
6+15=21
9+10=19
The solution is the pair that gives sum 19.
a=9
b=10
Rewrite 6y^2+19y+15 as (6y^2+9y)+(10y+15).
(6y^2+9y)+(10y+15)
Factor out 3y in the first and 5 in the second group.
3y(2y+3)+5(2y+3)
Factor out common term 2y+3 by using distributive property.
(2y+3)(3y+5)
