Answer:
<h2>-1</h2>
Step-by-step explanation:
2 - (-4) + (-y)
Substitute y = 7 to the expression:
2 - (-4) + (-7) = 2 + 4 - 7 = 6 - 7 = -1
Answer:
5/12
Step-by-step explanation:
Short answer: you don't.
The linear term in the numerator of the integral means the form shown is not applicable. Rather, you perform the integration using partial fraction expansion.

The integral is ...
... (1/35)ln|5x-1| +(6/35)ln|5x+13| +C
_____
If the numerator of your integral were a constant, then the fractions multiplying the separate partial fraction integrals would have the same magnitude and opposite signs. You would end with the difference of logarithms, which could be expressed as the log of a ratio as shown in your problem statement.
First we calculate surface of base.
10 * 6 = 60 feet^2
The Volume of pyramid is calculated by formula:
V = B*H/3
H- height of pyramid
B- surface of base of pyramid
We have both of those so all we have to do is to finish calculation:
V = 60*15/3 = 300 feet^3
Answer is 300 qubic feets
