Answer:
-x-3
Step-by-step explanation:
(x+3) + the additive inverse = 0
the additive inverse = -(x+3)
The sign of the leading coefficient can be found using the graph of a polynomial function.
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have given the graph of polynomial functions:
In the first graph:
The leading coefficient is positive.
x → ∞, f(x) → ∞
x → -∞, f(x) → -∞
Degree of a function = 3
In the second graph:
The leading coefficient is negative.
x → ∞, f(x) → -∞
x → -∞, f(x) → -∞
Degree of a function = 4
In the third graph:
The leading coefficient is positive.
x → ∞, f(x) → ∞
x → -∞, f(x) → ∞
Degree of a function = 4
In the fourth graph:
The leading coefficient is negative.
x → ∞, f(x) → -∞
x → -∞, f(x) → ∞
Degree of a function = 3
Thus, the sign of the leading coefficient can be found using the graph of a polynomial function.

Answer:
Hello there, the answer would be
Step-by-step explanation:
We cut the figure into two different shapes.
Since on one side it is 4 feet and the height is seven, we cut right there.
So the bottom figure is now 4 x 5 = 20
The top figure is cut with 3 height left, So all we do is just multiply.
8 x 3 = 24.
20+24=44.

Answer is a because a^-2 will be changed to 1/a^2
Hope that helps
