7x³-7x²
You have to divide each by the greatest common factor. In this case that is 7x²
So now you have 7x²(x+1). Now you set each factor to 0
x+1=0
x=-1
and
7x²=0
x=0
Your answers are x=-1 and x=0
Answer:
The radius of the cone is 9 units.
The height of the cone is 12 units
The volume of the cone is represented by the expression One-thirdπ(9)2(12).
The square root of 25 is b. 5.
This is because the square root of a number multiplied by itself equals the original number. Thus, the square root of 25 is 5.
1. -7(6v+4)+3v(v+3)
-42v-28+3v ²+9v
-33v-28+3v ²
=3v ²-33v-28
2. -3k(2k-3)+7(k-7)
-6k ²+9k+7k-49
= -6k ²+16k-49
