Answer:

b     3 was not multiplied by −4

Step-by-step explanation:

The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.

3(p − 4) = 3p + 3 × (-4) = 3p - 12

His attempt is

3(p - 4) = 3p - 4

He did multiply 3 by p, but h did not multiply 3 by -4.

Answer:    b     3 was not multiplied by −4
