Answer 1

hi can you send me the formula...let me teach you

Answer 2

• B. BD = 67

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
