Question

Square ABCD is shown below.

If BD = 8x - 50, and DE = 2x + 5, find BE.

A) 15

B) 35

C) 25

D) 45

Answer 1

35 is the length of BE

Explanation:

2(2x + 5) = 8x - 50

4x + 10 = 8x -50

10+50 = 8x-4x

60= 4x

15 = x

2x + 5 = length of BE equal to length of DE

2(15) +5 = BE

30 +5

35 is the length of BE
