Answer:
48
Step-by-step explanation:
92 is correct i did this and i got it correct
9/10 is equivalent to 90/100 and the answer under mine or above or the other answer should be reported. They got points for a question they did not answer correctly.
To check if the binomial is a factor, we take it in the
form of x – c = 0 and then x = c, then substitute the value of c into x on the
polynomial equation. It is only a factor when the value of f(x) = 0
a. x – 1
x = 1
Substitute x = 1 into the equation.
f(x) = 1^3 + 3 * 1^2 – 25 * 1 – 75
f(x) = -96
(not a factor)
b. x – 3
x = 3
Substitute x = 3 into the equation.
f(x) = 3^3 + 3 * 3^2 – 25 * 3 – 75
f(x) = -96
(not a factor)
c. x + 3
x = -3
Substitute x = 3 into the equation.
f(x) = (-3)^3 + 3 * (-3)^2 – 25 * (-3) – 75
f(x) = 0
(a factor)
d. x - 5
x = 5
Substitute x = 3 into the equation.
f(x) = 5^3 + 3 * 5^2 – 25 * 5 – 75
f(x) = 0
(a factor)
e. x + 5
x = - 5
Substitute x = 3 into the equation.
f(x) = (-5)^3 + 3 * (-5)^2 – 25 * (-5) – 75
f(x) = 0
(a factor)

Answer: H = {3, 5, 7}</h3>
Explanation:
We simply list any odd number that is between 2 and 8. The term "roster form" can be thought of as listing the roster of a sports team (eg: baseball). So instead of describing what the numbers look like, we list out the numbers themselves. Those numbers being 3, 5 and 7.
Something like {2,4,6,8} is ruled out because we're dealing with odd numbers only.
