Answer:
135
Step-by-step explanation:
15 x 9 = 135
A = (1/2)(b * h)
It is 1/2 times the product (which is the end result of multiplication of two values), of base (b) times height (h)
Diagonals of rectangles are equal. AC = BD, so 2(x-3) = x+5. 2x - 6 = x+5. x = 11. Plug this into x+5 and you get 11 +5 = 16.
