Answer:
w = 13yd, l = 18yd
Step-by-step explanation:
let x be width, so x+5 = length
Perimeter is sum of all 4 sides, and since opposite sides equal in rectangle,
P = 2(l+w)
= 2(x+5 +x)
= 4x + 10
Since perimeter is give as 62yd, equation is
4x + 10 = 62
4x = 52
x = 13
This answer would be b because
Answer:
40/9
Step-by-step explanation:
9y = -8x + 40
y = -8/9x + 40/9
The answer is D.
6x * 6x = 36x^2
6x * -7 = -42x
6x * 7 = 42x
-7 * 7 = -49
The -42x and 42x cancel each other out, resulting in 36x^2 - 49.
