Question

pqrs is a square.if pq=8x-12 and qr=5x+18,find the length of each side of the square​

Answer 1

Answer:10

Step-by-step explanation:

pq=8x-12 and qr=5x+18

we know in square all sides are equal in length so pq=qr ps=rs

so

8x-12=5x+18

8x-5x=18+12

3x=30

x=30/3

x=10

Answer 2

The length of each side of the square​ is 68 units.

Step-by-step explanation:

Given information: pqrs is a square, pq=8x-12 and qr=5x+18.

We know that each side of a square are congruent.

$pq\cong qr$

$pq=qr$

Substitute pq=8x-12 and qr=5x+18.

$8x-12=5x+18$

Isolate variable term on left side.

$8x-5x=12+18$

$3x=30$

Divide both sides by 3.

$x=10$

$pq=8(10)-12=80-12=68$

Therefore, the length of each side of the square​ is 68 units.
