<span>You are given a rectangular picture measuring 8 inches by 7 inches. Also, Alistair wants this to be framed and that the total area is 34 square inches. The width of the frame is x inches. To solve the dimension of the frame with value of x we have:
We have to assume that x here will be equal to all sides of the frame and so, using the area of the rectangle, we can model the equation like this:
A = LW (where A is the area, L is the length and W is the width)
36 = (8 - x)(7 - x)
36 = 56 - 8x - 7x + x</span>²
<span>x</span>² - 15x +20 = 0 → model of our equation and in quadratic form
x² - 15x + 20 = 0
using a calculator, x = 1.48 inches

3.Use the equation you created in part A to find the width of the picture frame</span>
Answer:
neither
Step-by-step explanation:
they are parallel when they have the same slope and perpendicular when the slope is completely different
Answer:
(-2, -4)
Step-by-step explanation: because its going backwards it should be a negative slope :)
I'm sorry if I'm wrong but i hope this helps :)
Answer:
- increase the sample size
- choose students from different grade levels
- choose every fourth student in all language arts classes
Your welcome :]
