Extra points! please help !!

Xelga [282]

Answer:

The maximum width of the pool must be 38 ft

Step-by-step explanation:

Let

y -----> the length of the swimming pool

x ----> the width of the swimming pool

The perimeter of the swimming pool is

$P=2(x+y)$

we have

$y=22\ ft$

substitute

$P=2(x+22)$

$P=2x+44$

Remember that

The perimeter of the pool must be no more than 120 feet

so

The inequality that represent this scenario is

$2x+44 \leq 120$

Solve for x

$2x \leq 120-44$

$2x \leq 76$

$x \leq 38\ ft$

therefore

The maximum width of the pool must be 38 ft
