Factor the GCF: 9x4y − 6x3y2 + 3x2y3.

Ganezh [65]

For this case we have the following expression:
$9x^4y - 6x^3y^2 + 3x^2y^3
$
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:
$3x^2y
$
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:
$3x^2y (3x^2 - 2xy + y^2)
$
Answer:
the GCF is:
$3x^2y (3x^2 - 2xy + y^2)$
option A: a 3 is missing at the beginning of the option.

Step-by-step explanation:

7x+4y=-4 *-2 7x+4y=-4 *-2 = -14x-8y=8

5x+8y=28

-14x-8y=8 x=-4, y=6

-9x=36

x=-4

7(-4)+4y=-4

-28+4y=-4

4y=24

Your friend has $100 when he goes to the fair. He spends $10 to enter the fair and $20 on food. Rides at the fair cost $2.00 per

zysi [14]

You could use the function:

f(x)=30+2x
100=30+2x

In which lets say he rode 3 rides. Plug in 3 for x.

100=30+2(3)

Then Multiply
100=30+6

Then combine 30 and 6 to get 36.
Then you can subtract 36 from 100 to get
$64 left over.
