The associative property because you are moving the parentheses
Answer:
Jalen lost 12 pounds in the first 3 weeks
12/3=4 per week
than the weight loss slowed by half, meaning he lost 6 pounds in 3 weeks
6/3=2 per week
84-12=72 to loose after 3 weeks
72/2=36 weeks
to loose 84 pounds you need 3+36=39 week
pls mark me as brainlist
F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.
