Answer:
C and D
Explanation:
Remember that when you are working with parentheses, you have to hand out whatever variable, sign, or number is outside of it.
Because 16 times 20 does not equal 36, we can say that A is not correct.
Because x(16 + 36) = 16x + 36x, B is not correct either.
Because 4(4x + 9) = 16x + 36, C is correct.
Because 2(8x + 18) = 16x + 36, D is correct.
Because 2(8x + 36) = 16x + 72, E is not correct.
Therefore, C and D are equivalent to the expression
