Question

Rewrite in simplest terms: minus, 3, left bracket, 7, f, plus, 3, f, plus, 9, right bracket, minus, 4, f−3(7f+3f+9)−4f

Answer 1

To simplify the expression -3(7f+3f+9)-4f, distribute the -3 across the terms inside the bracket, combine like terms, and then add the -4f. The simplified expression is -34f - 27.

Step-by-step explanation:

The expression given is -3(7f+3f+9)-4f. To simplify this expression, follow the steps below.

Distribute the -3 across the terms inside the bracket: -3 × 7f gives -21f, -3 × 3f gives -9f, and -3 × 9 gives -27.

Combine the distributed terms: -21f - 9f - 27.

Add like terms: Combine -21f and -9f to get -30f.

Then add the -4f that is outside the bracket to the -30f to get -34f.

So the simplified expression is -34f - 27.
