Hi can you help me with this I'm not sure i understand how to solve it....

OpenStudy (anonymous):

OpenStudy (anonymous):

wait a sec i'm not tagged

OpenStudy (anonymous):

nvm

OpenStudy (anonymous):

oh you can help @Molly_Qian

OpenStudy (anonymous):

:P ok so uh what do you need help on?

OpenStudy (anonymous):

OpenStudy (anonymous):

That^

OpenStudy (anonymous):

I was thinking it was the first one

OpenStudy (anonymous):

lol ok so uh what can you get from that?

OpenStudy (anonymous):

\((x-2)\times 4\)

OpenStudy (anonymous):

simplify... you get \(4x-8\)

OpenStudy (anonymous):

you add up all the sides and multiply x times that and then multiply the sides added together by 2 and subtract that

OpenStudy (anonymous):

and see if you can match it with one of the answers... like the first one or something

OpenStudy (anonymous):

it doesn't have to be that complicated u know

OpenStudy (anonymous):

O ok

OpenStudy (anonymous):

OpenStudy (anonymous):

something like that

OpenStudy (anonymous):

i fu look at it this way u can see that the frame is made up of 4 parts

OpenStudy (misty1212):

HI!!

OpenStudy (anonymous):

and each part... is \(x-2\)

OpenStudy (misty1212):

it is looking for the area

OpenStudy (misty1212):

you are supposed to compute \[(x+4)^2=(x+4)(x+4)\]

OpenStudy (anonymous):

HI

OpenStudy (anonymous):

but isn't that a bit too complicated?

OpenStudy (misty1212):

oh no nvm i read it wrong

OpenStudy (misty1212):

you just want the area of the frame right?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

ughh i already solved it if u hadn't realized...

OpenStudy (misty1212):

what did you get?

OpenStudy (anonymous):

a

OpenStudy (anonymous):

Oh okay thank you both!!

OpenStudy (anonymous):

\((x-2)\times 4\) \(=4x-8\) \(=8x-16\)
