Answer 3

To expand the expression and remove the parentheses, follow the distributive property:

-7(5 - a - 4b)

First, distribute -7 across each term inside the parentheses:

-7 * 5 = -35 -7 * (-a) = 7a (negative multiplied by negative becomes positive) -7 * (-4b) = 28b (negative multiplied by negative becomes positive)

Now, combine the terms:

-35 + 7a + 28b

The final expression after expanding the parentheses is:

7a + 28b - 35
