Trying using photo math or on google there is actually a slope calculator called functions calculator in stupid sorry for not answering it lol
Answer:
48
Step-by-step explanation:

is basically the horizontal axis.
First, find the integral of x^2-25.
Remember that
integral of a constant is that constant times x.
Also that
to take the integral of a power function, add 1 to the degree and divide by that same degree.

We then get

Evaluate at -3


Then we evaluate at 0

Next, we subtract the the answer then we get

Answer:
x² + 3x - 28
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(x + 7)(x - 4)
= x(x - 4) + 7(x - 4) ← distribute both parenthesis
= x² - 4x + 7x - 28 ← collect like terms
= x² + 3x - 28
They are both the same because anything times 0 equal 0 and 0+0 equals 0.
