You will need to drain 1016.308 gallons an hour
1=2x^2-7
2x^2=8
x^2=4
so x=2 or x=-2
Answer:
550
Step-by-step explanation:
First substitute the numbers
(4*6)^2-36/6=
24^2-36/6=
24^2-6=
556-6=
<u><em>550</em></u>
Answer:
x = 9
Step-by-step explanation:
Create an equation:
x = some number
and = add
other number = -15
x + (-15) = -6
remove () using rule
x - 15 = -6
add +15 to both sides
x = 9
The area:

Substitution: u = - 6 x
du = - 6 dx
dx = -1/6 du
∫ -1/6 e^(u) du = - 1/6 e^(u) = - 1/6 e^(-6x)

=
π / 3
