Answer:
A- Margaret gre at a faster rate than Donavan
Step-by-step explanation:
You know that the square root of 144 is 12 and 169 is 13. 150 is in between 144 and 169 so its square root must be between 12 and 13.
Given:
square shape.
diagonal = 44 inches
The frame is square shape therefore its side lengths are equal. We need to solve for the side length using the diagonal.
a = √2 d/2
a = √2 44/2
a = √2 22
a = 1.414 * 22
a = 31.112 or 31 inches
Perimeter: 31 inches * 4 sides = 124 inches
You probably just need to simplify the expression. To do this you just combine like terms. So you would subtract 38 from the 10 to get -28x and then subtract 47 from 36 which gives you -11. Your expression should be -28x-11.<span />
