If x = 3, find the value of x2 + 2x
Answer:
15
Step-by-step explanation:
[tex]x^{2} + 2x = 3^{2} + 3 * 2 = 9 + 6 = 15[/tex]
3 · 2 = 6
2 · 3 = 6
6 + 6 = 12

There were 110 students at a creative writing workshop last year. This year there are 132 students. What is the percent of increase in the number of students at the workshop?
Answer:
20% increase
Step-by-step explanation:
the initial number is 110 so lets take that as a 100%
the final number is 132 and it will be x
110/132=100/x
we multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.
110*x=132*100
110x=13200
x=120
Then we deduct 120 by 100 to know how much the percent increase is
(120-100)%=20% :)

Find the slope of the line that passes through (-68, 47) and (-66, 33).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Quick please
Answer:
- 7Step-by-step explanation:
The slope formula:
[tex]m=(y_2-y_1)/(x_2-x_1)[/tex]Substitute the values to get:
[tex]m=(33-47)/(-66+68)=-14/2=-7[/tex]_________
[tex] \: [/tex]
(X1, X2) = (-68, 47)
(Y2, Y1) = (-66, 33)
Soo :
m = [tex]\frac{Y2 - Y1}{X2 - X1}[/tex]
m = [tex]\frac{33 - 47}{68 - 66}[/tex]
m = [tex]\frac{-14}{2}[/tex]
m = [tex]\boxed{\bold{-7}}[/tex]

A bowling alley charges a flat fee to rent shoes. There is an additional fee for each game played. The function y=2.5x+3
represents the cost y of bowling x games. Interpret the parameters of the function.
represents the shoe rental charge.
represents the price per game.
The number that represents the shoe rental charge is 3.
The number that represents the price per game is 2.5.
The equation provided is a linear equation. A linear equation is made up of one varaible that has a power of one.
y= 2.5x + 3
In the given equation, 2.5 represent the additional fee for each game played. This number increases with each game played.
When:
1 game is played, the additional fee is 2.5 x 1 = 2.50.10 games are played, the additional fee is 2.5 x 10 = 25.3 is the flat fee to rent the shoes. It is a constant cost that does not change with the total games played.

Find the radius of a cube whose volume is 994 cubic centimeters.
Using work to find the radius
Answer:
Side of the cube: 10cm
Step-by-step explanation:
Firstly, I'd like to state that cubes actually do not have a radius, they have sides. Hence, I am going to solve for sides below:
Volume formula for a cube:
v = s³
Since the volume is 994 cm³
s³ = 994
s = [tex]\sqrt[3]{994}[/tex]
= 9.97995986613
≈ 10cm

Answer for 33 = 1, 3, 11, 33.
This is because all of those numbers divide into 33 evenly / are factors of 33.
Answer for 93 = 1, 3, 31, 93
This is because all of those numbers divide into 93 evenly / are factors of 93.
Answer:
1) composite: 1, 3 , 11 , 33
2) composite 1, 3, 31, 93
Step-by-step explanation:
1) We know that 33 is divisible by 3 because the whole value is equal to 6, and the last digit is a 3.
2) We know that 93 is divisible by 3 because the last digit was 3, and all of the place values added up to 12, which is also divisible by 3.

What is the quotient of 6.591 times 10^7 6 and 8.45 times 10^2 expressed in scientific notation?
Answer:
7.8 x 10^4 or 7.8e4 hope this helps!
The quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.
What is quotient?In arithmetic, a quotient is a quantity produced by the division of two numbers.
Given is to find the quotient of 6.591 x 10⁷⁶ and 8.45 x 10².
We have to find the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10².
6.591 x 10⁷⁶ ÷ 8.45 x 10²
(6.591 x 10⁷⁶/8.45 x 10²)
(6.591 x 10⁷⁶ ⁻ ²)
6.591 x 10⁷⁴
Therefore, the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.

Answer:
3*r = 3
Step-by-step explanation:
[tex]\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r[/tex]6 is a solution.
[tex]3*r=3\\\r =\dfrac{3}{3}\\\\r = 1\\[/tex]
6 is not a solution.
[tex]7r = 42\\\\r =\dfrac{42}{7}\\\\r = 6[/tex]
6 is a solution
Answer:
My best answer is A
Step-by-step explanation:
if you plug in 6 for r, it doesn't work for A.
B is hard to see so can't tell
C works with r=6, so it's not C
and D works as well, so it's not D
