HI!!

OpenStudy (lisa2345):

I think 25 is D

OpenStudy (lisa2345):

i'm not sure on 26

OpenStudy (misty1212):

this is really algebra the area is base times height, they want you to do \[(5x+3)(x-2)\]

OpenStudy (misty1212):

the answer is an algebraic expression, not a number

OpenStudy (lisa2345):

huh? lol

OpenStudy (misty1212):

oh i see you are saying the answer to number 25 is the choice D \[5x^2+13x+6\] but that is not right

OpenStudy (lisa2345):

how is that? I did the foil method. :/

OpenStudy (misty1212):

lol foil ok i think you ignored the minus sign

OpenStudy (misty1212):

it is not \[(2x+3)(x+2)\] which would give you that one, it is \[(5x+3)(x-2)\]

OpenStudy (lisa2345):

OHHHHHHHH

OpenStudy (lisa2345):

its b

OpenStudy (misty1212):

yes it is

OpenStudy (lisa2345):

I need help with 26 now ;/

OpenStudy (misty1212):

perimeter is twice the base plus twice the height |dw:1433784951833:dw|

OpenStudy (misty1212):

you have to do \[2(5x+3)+2(x-2)\] multiply out, combine like terms

OpenStudy (lisa2345):

its C? @misty1212
