Multiply -7 * 8x @rocky1718

OpenStudy (anonymous):

7*8 IS 56 @iGreen.

OpenStudy (anonymous):

No, that's -7, not 7.

OpenStudy (anonymous):

So it's actually -56x. What's -7 * -3?

OpenStudy (anonymous):

??

OpenStudy (anonymous):

7 is NEGATIVE And NEGATIVE 7 times 8 is NEGATIVE 56

OpenStudy (anonymous):

OK , and -7*-3 is +21 right

OpenStudy (anonymous):

@iGreen.

OpenStudy (anonymous):

Yep, you got it.

OpenStudy (anonymous):

So we have: -56x + 21 + x And what's -56 + 1?

OpenStudy (anonymous):

50

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

-56 + 1 is the same as 56 -

OpenStudy (anonymous):

OpenStudy (anonymous):
