The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
From the prism:
Perimeter P = 2(w + l)
40 = 2(w + l)
w + l = 20 (1)
Also:
Base area (B) = wl
100 = wl (2)
from equation 1 and 2:
w = 10, l = 10
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.

The given function is

And we have to find the value of g(0), and for that we put 0 for x in the given equation.
And on substituting 0 for x in the given expression, we will get


So for the given function, the value of g(0) is -4 .
The answer is 10 because its close to the answer by multiplying those two fractions
