Question

F(x) = 3x -6 What is 7 times f(x)​

Answer 1

21x - 42, see below :)

Explanation:

Hello!

We know that f(x) is equal to 3x - 6

We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6

7 * f(x)

7(3x-6)

We use distributive property to open the parenthesis:

7 * 3x + 7 * -6

21x - 42

Answer 2

21x - 42
