Answer:
x^2 -2x -35 = 0
Step-by-step explanation:
Lets's solve backwards
x = -5
Add 5 to both sides
x + 5 = 5 - 5
x + 5 = 0
and
x = 7
Subtract 7 from both sides
x - 7 = 7 - 7
x - 7 = 0
Finding the product of both linear functions
(x + 5)(x - 7) =0
x^2 -7x + 5x -35 =0
x^2 -2x -35 = 0
It is a function, because you are associating one and exactly one y-value to each x-value.
H, r
Surface Area = 2πrh
If the h, is now h/3 and the r, now r/3
Surface Area = <span>2π*r/3*h/3
= </span><span>2πrh/9
</span><span>
The modified surface area is reduced by 9 times.
