ANSWER

B. 8w - 10 = 174

Step-by-step explanation

The length of the rectangle is 5 less than 3 times the width.

Let the length be L.

Let the width be w.

This means that:

L = 3 * w - 5

L = 3w - 5

The perimeter of a rectangle is given as:

P = 2(L + w)

The perimeter of the rectangle is 174. This means that:

174 = 2L + 2w

Recall:

L = 3w - 5

=> 174 = 2(3w - 5) + 2w

174 = 6w - 10 + 2w

=> 8w - 10 = 174

That is Option B
