OpenStudy (anonymous):

Nnesha (nnesha):

you have variable you cannot combine

OpenStudy (anonymous):

oh dear your answer should have a \(d\) in it where did the \(d\) go?

Nnesha (nnesha):

|dw:1417582879497:dw| multiply -3 by b and then -3 times -7

OpenStudy (anonymous):

b+-10

OpenStudy (anonymous):

\[-3(b-7)=-3\times b+(-3)\times (-7)\] is the first step

Nnesha (nnesha):

let me know what you get

OpenStudy (anonymous):

-3b and 21

Nnesha (nnesha):

yes right :) )

OpenStudy (anonymous):

so it would be 18b

OpenStudy (anonymous):

@Nnesha

Nnesha (nnesha):

nope you cannot combine them because -3 have variable and 21 doesn't so your final answer is -3b+21

OpenStudy (anonymous):

Nnesha (nnesha):

yep :)
