Gcf for the set of numbers 10,15, and 30​

GCF=5

Step-by-step explanation:

10 = 2 * 5

15 = 3 * 5

30 = 2 * 3 * 5

The greatest common factor is 5

Step-by-step explanation:

the factors of 10 are 1, 2, 5, 10

The factors of 15 are 1, 3, 5, 15

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30

The one number they all have is 5 so the GCF of 10, 15 and 30

would be 5.

-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
