The perimeter of ▭pqrs is 186. find the length of each side of ▭pqrs under the given conditions: rs = sp − 7.

The formula of a perimeter of ▭PQRS is equal P = 2|RS| + 2|SP|.

We have:

P = 186

|RS| = |SP| - 7

Substitute

2(|SP| - 7) + 2|SP| = 186      |:2

|SP| - 7 + |SP| = 93     |+7

2|SP| = 100    |:2

|SP| = 50

|RS| = 50 - 7 = 43

50, 43, 50, 43.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
