Question

In parallelogram ABCD, BC=3x-1, AB=x+11, and AD=2x+2. What is the value of x?

Answer 1

Answer: 3

Explanation:

Answer 2

x = 3

Explanation:

A property of a parallelogram is opposite sides are equal and parallel.

Hence BC = AD ← opposite sides, thus

3x - 1 = 2x + 2 ( subtract 2x from both sides )

x - 1 = 2 ( add 1 to both sides )

x = 3
