Question

use the distubitive property to write an expression that is equivilent to 7(3×-4)

Answer 1

Multiply the 7 in to each part of the parenthesis. So 7(3x-4) would be the same as 7(3x) - 7(4).

This can be simplified as:
21x - 28
Which is your answer.

take the 7 and multiply is with everything in the parenthesis
21x-12
