Use long division for dividing
Here 'v' term is missing so we use 0vW
Divide 
by v-10 using long division
Step 1: Put 8v^2 at the top
step 2: multiply 8v^2 with v-10 and put it at the bottom
step 3: subtract it
We will get remainder 6
so quotient is 
Remainder is 6
V = pi * r^2 *h
where r is the radius and h is the height of the cylinder
V = pi * 7^2 *4
V = pi* 49*4
pi is approximated by 3.14 or 22/7
V = 22/7 * 49 * 4
V = 616 units ^3
what multiplied by what is 15 but added together is 8

Answer: a
The answer is D 105 because i know
3a+b+c
The perimeter is two times one side (to account for the opposite) and two times the adjacent side. So if the sides would be x and y, the perimeter would be 2*x + 2*y.
So, knowing that the sum is 16a+8b-6c, if we subtract the given side 5a+3b-4c from this, what remains is two times the "other" side:
16a+8b-6c - 2*(5a+3b-4c) =
16a+8b-6c -10a-6b+8c =
6a+2b+2c
half of that is
(6a+2b+2c)/2 = 3a+b+c
