Can someone me factor the gcf out of the expressions! you! you dont have to do all. : )

Step-by-step explanation:

1) -10v^4 - 60 v³ - 70v involves the common factor -10v in all three given terms.  Thus, -10v is the GCF.  The quotient is v³ + 6v² +7.

2) 12m^5 + 36m^3 + 40m²     Here we can see that 12 is common to the first two terms but not to the third one.  4m² is common to all three terms, resulting in a quotient of 3m³ + 9m + 10

3) 10n² + 50n - 80 clearly features 10 as a factor common to all three given terms.  Factoring 10 out, we get the quotient n² + 5n - 8.  The GCF is 10.

4) -18x^4 - 42³ + 42² has 6 as the GCF.  6 divided into -18x^4 yields -3x^4; 6 divided into 42³ yields 12348, and 6 divided into 42² yields 294.

Thus, -18x^4 - 42³ + 42² = 6(-3x^4 + 12348 + 294).

                                    -3 is also a factor common to all three terms within parentheses:               (6)(-3)(x^4 - 4116 - 98)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
