The answer to the equation is 30%
Answer:

Step-by-step explanation:
<u>Polynomials
</u>
a)
The polynomial whose graph is shown is of third degree because it has three real roots. The roots of a polynomial are the values of x that make the expression equal to zero. We can see it happens three times in the graph provided. The roots or zeros are
x=-2, x=1, x=3
b)
The factored form of a polynomial whose roots
are known is

We know the value of the roots, thus the polynomial is written as

We need to find the value of a. We do that by replacing the value of x=0 and finding a that makes f(0)=3 (as seen in the graph). Thus





Thus the factored form of the polynomial is

c)
Let's multiply all the factors





Answer:
9 3/8in thick
Step-by-step explanation:
(15*5)/8=
75/8=
9 3/8in thick
<span>If c = 30 and d = 8, then
2c + 4d
= 2(30) + 4(8)
= 60 + 32
= 92</span>
B I think that is the answer. If its not please let me know.
