Radius = diameter/2
35/2 = 17.5
Linear because there is a constant change (+3)
Answer:
The surface area applies to how much space a SOLID objects occupies while volume is the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains, so volume can be anything.
Step-by-step explanation:
you can't really write an essay-
Let x = your number.
(x - 17) * -7 = -35. Divide each side by -7.
(x - 17) = 5. Add 17 to each side.
x = 22.
Your number is 22
We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35.
Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.
So split the 2r into these two terms and group.
(5r^2 - 5r) + (7r - 7)
Factor both groups.
5r(r-1) + 7(r-1)
The factors of (r-1) can be added together to get the answer.
(r-1)(5r+7)
