The answer is 2x(2x²+x+1).
When we subtract polynomials we combine like terms:
(9x³+2x²-5x+4)-(5x³-7x+4)
9x³-5x³=4x³
2x²- 0 = 2x²
-5x--7x=-5x+7x=2x
4-4=0
This gives us
4x³+2x²+2x
Each of these is divisible by 2, and each has an x, so we factor those out:
2x( )
4x³/2x = 2x²:
2x(2x² )
2x²/2x=x:
2x(2x²+x )
2x/2x = 1:
2x(2x²+x+1)
You have to plug in the given numbers and perform each operation. Let me know if you have questions. The answers are circled.

X= 3
Step-by-step explanation:
apply -(-a)=a rule
-23+4*8/3
-23+4*8=9
9/3
=3
2y-(3)=-19
y= -8
Answer:
She would need 144 square feet of carpet.
Step-by-step explanation:
Since the pen is 12 feet by 12 feet you would multiply 12 by 12 for your answer of 144 square feet.
Your total volume would be 150 cubic feet and the weight would be .1
