Answer:
Yes
Step-by-step explanation:

Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :

One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :

So, the other factor is (3-x).

well, the last part will be with a calculator, but you can simply use the area in π terms.
Answer:
(x^2-9)
Step-by-step explanation:
Well, using FOIL you can put an polynomial in standard form.
Equivalent Expressions are expression that have the same value on both side of the equal sign.
Expression 1:
First simplify both sides of the expression. One of them are already fully simplified.
8x-4y=4(-y+2x)
8x- 4y=-4y+8x
This expression IS an equivalent expression.
Expression 2:
Do the same as in expression one (we will be simplifying all of the expressions).
8x+4y=4(2x+y)
8x+4y=8x+4y
This expression IS an equivalent expression.
Expression 3:
4x-8y=4(-x+2y)
4x-8y=-4x+8y
This expression IS NOT an equivalent expression.
Expression 4:
4x+8y=4(x+2y)
4x+8y=4x+8y
This expression IS an equivalent expression.
Expression 5:
4x+8y=4(8xy)
4x+8y=32xy
This expression IS NOT an equivalent expression.
