2x - 15 = -27
2x = -27 + 15
2x = - 12
x = -12/2
x = -6 <==
The perimeter of this square is 220, so:
2L + 2w = 220
w = 2/3 L
We can input the w:
2(2/3 L) + 2w = 220
10/3L = 220
10L = 660
L = 66
The width is 44
The length is 66

Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as
where k is the constant of variation
when y = 9
x = 4
We have
k = yx²
k = 9(4)²
k = 9 × 16
k = 144
So the formula for the variation is
when y = 1
Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
Hope this helps you.
There is no one answer (ordered pair) to this equation and the answer is found by graphing or trying out different values for each variable. Anyway, here are some solutions; (1,0), (4,1), (0,-1/3).
