Answer:

  • B.  BD = 67

Step-by-step explanation:

ABCD is a square.

BD and AC are diagonals and they have equal length.

We have AC = 7x + 18 and BD = 10x - 3

Since AC = BD, we substitute their values and solve for x:

  • 7x + 18 = 10x - 3
  • 10x - 7x = 18 + 3
  • 3x = 21
  • x = 21/3
  • x = 7

Then find the length of BD:

  • BD = 7x + 18 = 7*7 + 18 = 49 + 18 = 67

Correct option is B.  BD = 67
