Question

Which expression is equivalent to the following: *
20x+9y

Answer 1

B. 5(4x+2y)-y

Explanation:

Bring the 5 over and multiply

5×4 = 20 + x

=20x (thats the beginning of the expression)

5×2 = 10

10y - y = 9 because the - y is basically telling you to get rid of one of the y values so 10 - 1 = 9y
