Answer:
C. 540 in^3
Step-by-step explanation:
What you do is you use the formula V=lwh.
All your doing id=s multiplying them together.
V=18*10*3=540 in^3.
An exponent is when you have a coefficient that has a number attached to it that hangs out just above it.
so, if your last one is truly written like this: (-4)², the "2" is your exponent.
Answer:
95 degrees
Step-by-step explanation:
A supplementary angle is an angle that equals 180 degrees. Here it shows that 85 degrees + x = 180 degrees, since part of the supplementary angle has already been taken up by the 85 degrees and x is remaining. Therefore, solve the equation for x.
85 + x = 180
x = 95
Answer:
y=2
Step-by-step explanation:
12+8y=28
subtract 12 on both sides
8y=16
divide both sides with 8
![\frac{8y}{8} =\frac{16}{8}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B8y%7D%7B8%7D%20%3D%5Cfrac%7B16%7D%7B8%7D%5C%5C%5C%5C)
y=2
plug in 2 for y back to the original equation to double check if its right
12+8(2)=28
28=28
hope this helps
idk theres an "x"
