Answer:
(v+8)8 is 8v + 64
Step-by-step explanation:
Because You have to multiply whats outside the parentheses by whats inside them. Since you cant multiply 8 times x because you don't know x value you just put 8x.
Answer: Therefore, the x-intercept of the line is 0
A line with slope 2/3 contains the point P(-18, -12). What is the x intercept of the line?
Step-by-step explanation:
Given;
Slope m = 2/3
Straight line equation is given as
y = mx+c
Where m = slope and c = intercept on y axis
For this case,
y = 2/3x + c .....1
At point (-18,-12), Eqn 1 becomes;
-12 = 2/3(-18) + c
-12 = -12 + c
c = 0
The straight line equation becomes
y = 2/3x + 0
Therefore at y = 0 the value of x = 0
Therefore the intercept is at (0,0)
Therefore, the x-intercept of the line is 0

Answer:
180 cubic millimeters
Step-by-step explanation:
The volume of a hexagonal prism can be found with the following formula:
The area of a hexagon is:
Upon, closer inspection, you'll notice that the formula for area of a hexagon is in the formula for volume of a hexagonal prism.
We already know the area of the hexagon base, so we can just plug it in into the volume formula.
V=30h
We ale aso know the height, which we can plug in.
V=30(6)
Simplify.
V=180
Bh + hr = 25
you can factor out an h from the left side of your equation:
h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r
