Answer:
1,286.1 units is the answer
Step-by-step explanation:
your answer may vary depending on what you use for pie, using a calculator with pie on it gave me approx. 1286.79635
volume formula: V=πr^2h
so π*6.4^2*h
π*40.96*10
3.14*409.6
1,286.144
round
1,286.1
There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>
6x−12+2x=3+8x−15
Simplify:
6x+−12+2x=3+8x+−15
(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)
8x+−12=8x+−12
8x−12=8x−12
Subtract 8x from both sides.
8x−12−8x=8x−12−8x
−12=−12
Add 12 to both sides.
−12+12=−12+12
0=0
The real numbers are the only solution we can have.
D. Because it corresponds to the angle to the left
