Answer:
The answer is increased by 9
Step-by-step explanation:
X³(- 9x - 7) - 4x⁴
Distribute the x³:
- 9x⁴ - 7x³ - 4x⁴
Combine like terms:
- 13x⁴ - 7x³
Remove a common factor in x³ for your answer(s):
x³(- 13x - 7)
or
- x³(13x + 7)

equation for area of cylinder- A=2πrh+2πr2
Answer: (9+10x)(9-10x). Explanation: To factor this, look for numbers that can be FOILed (first, outer, inner, last). You know what if you separate the equation into two different parenthesis, one has to be negative and the other positive because there are no x^1 variables. 81 is equal to 9*9, and 100x^2 is equal to 10x*10x. Split these into two parenthesis, and add corresponding negatives. The answer should be (9+10x)(9-10x).
