Simplify the expression below.
(3f - 2g) - (18g + 11f)
OpenStudy (anonymous):
?? could you take out the parenthesis's, haven't done geometry in 2 years
OpenStudy (anonymous):
These are the possible answers...
-20g - 8f
-20g + 14f
-15g - 13f

OpenStudy (anonymous):
-30x-12y + 36x-12y
OpenStudy (anonymous):
Im alright at english. I like history and science but its kinda hard
OpenStudy (anonymous):
shuld be easy to solve
OpenStudy (anonymous):
-18x2y2
6x - 24y
6x2 - 24y2
6x + 2y
I think its B
OpenStudy (anonymous):
Right?

OpenStudy (anonymous):
ah.
OpenStudy (anonymous):
you cant simplify without a common factor. e.g. 7x^2y^2 -5x^2y^2=2x^2y^2
OpenStudy (anonymous):
Im so confused.
OpenStudy (anonymous):
@darsheva
OpenStudy (anonymous):

Simplify the expression below.
-3(10x + 4y) + 6(6x - 2y)
OpenStudy (anonymous):
6x
OpenStudy (anonymous):
nothing else ut 6x, y's cancel each other out
OpenStudy (anonymous):
-3 * 10 -3 * 4
OpenStudy (anonymous):
-18x2y2
6x - 24y
6x2 - 24y2
6x + 2y

6*6 6*2
OpenStudy (anonymous):
I think its B
OpenStudy (anonymous):
then do the rest, which i think you can do by yourself
OpenStudy (anonymous):
Next question?
OpenStudy (anonymous):
its neither, the y's cancel, and the\[-18x^2y^2\] theres no simplifying that except -18xy(xy)

I really need help!
OpenStudy (anonymous):
and im telling you the answer.
OpenStudy (anonymous):
to the -18x^2y^2
OpenStudy (anonymous):
is there a none of the above answer?
OpenStudy (anonymous):
Okay.
next question

Nope. just those 4.
OpenStudy (anonymous):
parabola with the grpah raised up 4 unites.
OpenStudy (anonymous):
