Question

Parallelogram PQRS with PS = -1 + 4x and QR = 3x + 3. What is the length of QR?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

PQRS

PS = -1 + 4x

QR = 3x + 3

QR = ?

Step 02:

PS = QR

-1 + 4x = 3x + 3

4x - 3x = 3 + 1

x = 4

QR = 3(4) + 3

= 12 + 3

= 15

The answer is:

QR = 15
