Rewrite in simplest terms:−3(7f+3f+9)−4f

To simplify the expression −3(7f+3f+9)−4f, we can first combine like terms inside the parentheses:

7f + 3f = 10f

Therefore, the expression becomes:

−3(10f + 9)−4f

Next, we distribute the -3 to each term inside the parentheses:

-3 x 10f = -30f

-3 x 9 = -27

Now the expression becomes:

-30f - 27 - 4f

Finally, we combine like terms:

-30f and -4f = -34f

Therefore, the final simplified expression is:

-34f - 27
