3. Which of the following are possible dimensions for the rectangle shown below that has an Area of 3𝑎2 + 9𝑎.
CIRCLE ALL THAT APPLY!
(A) 𝑙 = 3, 𝑤 = 𝑎2 + 3𝑎
𝑤
(B) 𝑙 = 3, 𝑤 = 3𝑎2 + 𝑎
(C) 𝑙 = 3𝑎, 𝑤 = 𝑎 + 3
𝑙 𝐴 = 3𝑎2 + 9𝑎
(D) 𝑙 = 𝑎, 𝑤 = 3𝑎 + 9
(E) 𝑙 = 3𝑎2 , 𝑤 = 𝑎 + 3

(F) 𝑙 = 2 , 𝑤 = 6𝑎2 + 18𝑎
4. Mr. Kelly sets off a bottle rocket from the ground. The height of the rocket over time is modeled by the function
ℎ(𝑡) = −16𝑡 2 + 48𝑡, where t stands for time in seconds and the height off the rocket is measured in feet.
a. Find ℎ(2). Use a sentence to explain what it means in this context.
