Question

Which expressions are equivalent to 18x – 6? Select all that apply.

Answer 1

B, if you distribute you get 2(times) 9x which is 18x and 2x-3 which is -6

so that would be 18x-6

Answer 2

A, B, & E

A because 16.4x + 1.6x equals 18x.

B and E require that you use te distributive property therefore 2 times 9x equals 18 x and 2 times -3 = -6. For E 6 times 3x = 18x and 6 times -1 = -6
