Answer:

So, C, and D.. can easily be marked incorrect. This is because in the question it asks, "Atleast 16" This leaves us with answer choice A and B. Answer choice (A), is a closed circle, while answer choice (B) is an open circle.

Closed circles include the number at the end point (less than/greater than/equal to), and open circles do not (less than greater than).

answer choice A. Closed circle, shifting to the right.

Adam is building a rectanglar swimming pool. The perimeter of the pool must be no more then 120 feet. If the length of the pool

jasenka [17]

Answer:

$W\leq 38\ ft$

The maximum width must be $38\ ft$

Step-by-step explanation:

Let

L ----> the length of the rectangular pool

W ---> The width of the rectangular pool

we know that

$P\leq 120\ ft$

$P=2(L+W)$

$2(W+L)\leq 120$ ----> inequality A

we have

$L=22\ ft$

substitute the value of L in the inequality A

$2(W+22)\leq 120$

simplify

$(W+22)\leq 60$

$W\leq 60-22$

$W\leq 38\ ft$

The maximum width must be $38\ ft$
