160÷40 is 4 so i think the function f multiplies x by 4.
when x is 8, 8×4=32 so the answer shld be 32

Answer:
Step-by-step explanation:
If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said. 20=11+(3/5)x. Hopefully that makes sense. 3/5 of the previous score plus 11 is 20. Anyway, you can just solve this algebraic expression for x.
20=11+(3/5)x subtract 11 from both sides
9 = 3/5 x Multiply both sides by 5
45 = 3x then divide both sides by 3
15 = x And there you go.
(4c - 3d)(3c + d) =
= 12c² + 4cd - 9cd - 3d² =
= <u>12c² - 5cd - 3d²</u>
