Factor this trinomial completely.
2x + 10x + 8

4(3x+2)

Step-by-step explanation:

Find the GCF (greatest common factor).

GCF=2

Factor out the GCF.

Simplify.

2(x+5x+4)

Collect the like terms x and 5x.

2(6x+4)

Factor out the number 2, because 2*3=6 and 2*2=4.

2*2(3x+2)

Simplify to get the answer.

4(3x+2)

step-by-step explanation:

y=mx+b

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
