Answer:
The dimensions of the iphone are 2 inches by 7 inches.
Step-by-step explanation:
Given that,
The dimensions of an iPhone are x – 2 and x + 3.
The area of an iphone is 14 sq inches
We need to find the dimensions of the iPhone. It is in the shape of a rectangle. Its area is given by :
[tex]A=l\times b\\\\(x-2)(x+3)=14\\\\x^2-2x+3x-6=14\\\\x^2+x-6-14=0\\\\x^2+x-20=0\\\\x^2+5x-4x-20=0\\\\x(x+5)-4(x+5)=0\\\\(x-4)(x+5)=0\\\\x=4\ and\ x=-5[/tex]
Neglecting negative value
First dimension = (x-2) = (4-2) = 2 inches
Other dimension = (x+3) = (4+3) = 7 inches
Hence, the dimensions of the iphone are 2 inches by 7 inches.
F(x)= x^2 - 7x +12
The above equation is in standard form. Write the above equation in factored form
f(x) = (x-r1)(x-r2)
r1 represents first root, r2 represetnts second root
What are the roots?
Remember, x-r1 = 0 and x-r2=0
Answer:
f(x) = (x - 3)(x - 4)
Step-by-step explanation:
f(x)= x^2 -7x +12 factors immediately into f(x) = (x - 3)(x - 4
The roots are 3,4

Answer:
perimeter of square=4×side
perimeter of square =4×13cm
perimeter of square = 52cm
area of square = side²
area of square = (13cm)²
area of square = 169cm²
Answer:
52 cm / 169 cm²
Step-by-step explanation:
To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.
13 + 13 + 13 + 13 = 52
The perimeter is 52 cm.
The area is the length times the width of the shape, so we have to multiply 13 by 13.
13 · 13 = 169
The area is 169 cm².
The answer is the third option, 52 cm / 169 cm².
Good luck :)

it takes four jars of in to record the store's inventory for 12 weeks at that rate how many jars of ink do you need to keep track of inventory for 33 weeks
Answer:
11
Step-by-step explanation:
So every 12 weeks there are 4 jars right? right.
1.) Divide 33 by 12 and you will get 2.75
2.) Then multiply 2.75 by 4 and you will get 11!

Answer =
Determine the probability of drawing either a jack or a spade?
Write ydur answer as a reduced fraction.
Answer =
Answer:
First Answer = 2/13
Second Answer = 4/13
Step-by-step explanation:
1. There are 52 cards in a standard deck. There is also a total of 4 jacks and 4 queens of these 52 cards. So, the probability of drawing either a jack or a queen after one pick would be 8/52 = 2/13.
2. There are 4 jacks, and 13 spades. However, one of those jacks is a jack of spades. So, instead of 17 possible picks, one overlaps, resulting in 16 possible picks. This is represented by 16/52 = 4/13.
The probability of drawing either a jack or a queen is 2/13 or 15.38%. In turn, the probability of drawing either a jack or a spade is 15/52 or 28.84%
Since Jenelle draws one card from a standard deck of 52 cards, to determine the probability of drawing either a jack or a queen, and to determine the probability of drawing either a jack or a spade, the following calculations must be performed:
Jack + Queen = 4 + 48/52 = X2/13 = X0.1538 = XJack + Spade = 4 + 1115/52 = X0.2884 = XLearn more in https://brainly.com/question/17193366

The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle. The chord of a circle which passes through the centre of the circle is called the diameter of the circle.
The chart shows the results of 20 spins that Kristie made with a spinner.
Based on these results, what is the probability that Kristie's spinner will land on Mexico the next time?
Answer:
3 / 10
Step-by-step explanation:
The required outcome = mexico ; number of spins = 6 spins
Total possible outcomes = sum. Of all spins = (6 + 4 + 5 + 5) = 20
P(Mexico on next spin) = required outcome / Total possible outcomes
P(Mexico on next spin) = 6 / 20 = 3 / 10

Erica saw a skateboard on sale for $45.56. The original price of the skateboard was $75.99. What is the approximate percent discount on the skateboard? Round to the nearest whole percent.
Answer:
60%
Step-by-step explanation:
45.56/75.99 x 100 = 59.9
Rounded = 60%
Hello!
Discounts! I struggle myself with these, but a common method can help you find the price.
First, we'll subtract 45.56 from 75.99, to get our discount factor.
75.99 - 45.56 = 30.43
Now, we have to figure out the percentage of said factor. How much of 75.99 is 30.43. We must divide discount factor by original number.
30.43 ÷ 75.99 = 0.40044742729306 which would be equal to 40.044742729306%
Lastly we round 40.044742729306% to the nearest whole percent.
Our final answer is: 40%

Use the net to find the surface area of the prism.
96 in2
12 in2
24 in2
84 in2
Answer:
a. 96 in²
Step-by-step explanation:
The surface area of the prism = the sum of the area of each part of the net shown
✔️Area of the 2 equal triangles = 2(½*b*h)
b = 4 in
h = 3 in
Area of the two triangles = 2(½*4*3) = 12 in²
✔️Area of the rectangle 1 with the following dimensions:
L = 7 in
W = 3 in
Area = L*W = 7*3 = 21 in²
✔️Area of the rectangle 2 with the following dimensions:
L = 7 in
W = 4 in
Area = L*W = 7*4 = 28 in²
✔️Area of the rectangle 3 with the following dimensions:
L = 7 in
W = 5 in
Area = L*W = 7*5 = 35 in²
✅Surface area of the prism = 12 + 21 + 28 + 35 = 96 in²

Write the equation of the circle with the given information.
Center: (2,8)
Radius: 3
Answer:
(x - 2)² + (y - 8)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (2, 8 ) and r = 3 , then
(x - 2)² + (y - 8)² = 3² , that is
(x - 2)² + (y - 8)² = 9
