Question

What is the solution to this problem... Also help explain how you got the answer..

-9-9(2g+7)

Answer 1

so this is -9 minus 9(2g+7)?

Get rid of the parenthesis first. Instead of subtracting 9, change it to plus the opposite of 9, because that's what subtraction is.

-9 + -9(2g+7)

Now in order to get rid of the parenthesis, you have to multiply the opposite of 9 with both 2g and a positive 7.

-9 + -18g + -63

-9 times 2g is -18g.

-9 times 7 is -63, since a negative times a positive is a negative.

-18g + -72 = -18g - 72

So you get -18g + -72, which you can simplify to -18g - 72.

at least that's what I remember and that's what I would do...I haven't had school for a few months.

Answer 2

Umm yeah Im sorry I don't know =|

Answer 3

-9-18g-63

-72-18g

i think...

Answer 4

-9-9(2g+7)

-9 - 18g - 63

-18g - 72

This is a simplification of the expression, but what is it you want to do other than that?

Answer 5

-9-9(2g+7)= -18(2g+7)

Next, use the FOIL method:

-18 x 2g, -18 x 7

=-36g -126

Answer 6

i could do it for you but what does g mean?

You use PEMDAS on it.

Answer 7

-18g-72
