Question

Figure ABCD is a parallelogram. Parallelogram A B C D is shown. The length of A D is 5 x + 3 and the length of B C is 38. What is the value of x?

Answer 1

x=7

Explanation:

5x+3=38

subtract 3 on both sides

5x=35

divide 35 by 5

35/5=7

therefore x=7

Answer 2

Explanation:

In a parallelogram, opposite sides are equal and parallel.

AD = BC

5x + 3 = 38

Subtract 3 from both sides.

5x + 3 - 3 = 38 - 3

5x = 35

Divide both sides by 5

5x/5 = 35/5

x = 7
