1. x = 31
2. y = 5 + 23
3.
4. y = -7
5. x = -2 + 13
The second one is correct. 66/300 = x/100
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A
B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
Hello there!
To do this, we will take the square root from each side
4^2 would be 4
16 would be 4
4 = 4
I hope I helped!
