The answer is x2 + 2xy + y2.
The gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².
<h3>What is the Total Surface Area of a Rectangular Box?</h3>
Total surface area (TSA) = 2(wl+hl+hw), where:
- l = length
- w = width
- h = height of the box.
The amount of gift wrap needed to cover the whole box = total surface area of the rectangular box
l = 20 in.
w = 8 in.
h = 13 in.
Plug in the values into the formula for total surface area of a rectangular box:
TSA = 2(8×20 + 13×20 + 13×8)
TSA = 1,048 in.²
Therefore, the gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

Answer:
x^3/2 - 6x^1/2
Step-by-step explanation:
f(x) = x - 6
g(x) = x^1/2
g(x) * f(x) = x^1/2(x - 6)
g(x) * f(x) = x^3/2 - 6x^1/2
