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)
