Answer:

121f -31

Explanation:

parentheses first:

4(32f+1)-7(f+5)

(128f+4)+(-7f-35)

take out of parentheses(can only do when being added/subtracted)

128f + 4 -7f -35

add all non f terms together and add all f terms together

(do not add variable terms with non variable terms)

121f - 31

tip for certain situations:

-(4+5x) = (-4-5x)
