X+8/4-x+5/4
The first term in the series is a positive "x", and the third one is a "-x". Since these are opposites, they cancel out
x+8/4-x+5/4
8/4+5/4
13/4
4 1/4
I'm pretty sure you are :)
Answer:
C.
Step-by-step explanation:
Use the equation V=4/3(3.14)r^3.
You gave me the diameter of 16 millimeters so just divide it by 2 to get a radius of 8 then input it for the r.
V=4/3(3.14)8^3
Then just multiply it to get the answer of 2144.66058 and C. is the closest to this answer and that is why it is correct.
FOIL stands for first, outer, inner, and last.
So, you multiply the first terms together, the outer terms together, the inner terms together, and then the last terms together.
(b+3)(b-9)
b^2-9b+3b-27 Then simplify
b^2-6b-27
