Question

Can someone help with this

Answer 1

If it is a parallelogram, then AC = BD. Therefore we have the equation:

5x + 4 = 3x + 8 subtract 4 from both sides

5x = 3x + 4 subtract 3x from both sides

2x = 4 divide both sides by 2

x = 2

BD = 3x + 8

Put the value of x:

BD = 3(2) + 8 = 6 + 8 = 14

Answer: 14
