Answer:
<h2><u>
158 in²</u></h2>
Step-by-step explanation:
First we can write the equation to find the surface area of a rectangular prism
Now rewrite filling in variables

Solve. Keep in mind the order of operations
After solving, you should get 158.
Since these measurements were done in inches, we need to add inches/in to the end.
Also, since it is area, we need to add ²
<u>158 in²</u>
<u></u>

22x+1 where x would be Gail's age.
Answer: t = 6 s
Step-by-step explanation:
When Rose hit the water, the height of the jump is 0, so: h(t) = 0.
Resolving it, we have:
-16t² + 16t + 480 = 0
To simplify the second degree equation, divided it by 16:
-t² + t + 30 = 0
Now, solve the equation using Bhaskara:
Δ = 1² - 4. (-1) . 30
Δ = 1 + 120
Δ = 121
t = 
t₁ =
= - 5
t₂ =
= 6
Since time can be negative, it took t = 6s for Rose to hit the water.
