can anyone one help me out with this problem please ? (8x – 2) + (7x + 6) I am suppose to simplify

OpenStudy (anonymous):

drop parenthesis combine like terms. wanna try

OpenStudy (anonymous):

15x+4

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

do another one mia so that we know u understand

OpenStudy (anonymous):

True

OpenStudy (anonymous):

um m 5x^2 + 3x ) + ( 2x + 5) A) 5x^2+3x+2x+5 The answer 5x^2 +5x + 5

OpenStudy (anonymous):

am i right?

OpenStudy (anonymous):

absolutely correct

OpenStudy (anonymous):

great job

OpenStudy (anonymous):

That's correct

OpenStudy (anonymous):

now if you were subtracting the two sets of parenthesis each sign of that set changes. u got it

OpenStudy (anonymous):

I kind of get it but it is so confusing to me like this last problem I have they gave me a diagram and I have to come up with a polynomial to describes it

OpenStudy (anonymous):

second set only

OpenStudy (anonymous):

draw or attach if u would like me to walk u thru it

OpenStudy (anonymous):

7x right?

OpenStudy (anonymous):

it is #10

OpenStudy (anonymous):

for ur problem - no ur 5x is correct only can combine like terms

OpenStudy (anonymous):

#10?

OpenStudy (anonymous):

yes I just sent it on attchment

OpenStudy (anonymous):

so what did u get

OpenStudy (anonymous):

first how do you calculate perimeter of a figure

OpenStudy (anonymous):

I have no clue I dont know how to

OpenStudy (anonymous):

to find the perimeter just add upp all of the sides

OpenStudy (anonymous):

they =69

OpenStudy (anonymous):

no you are going to have a variable

OpenStudy (anonymous):

:( I am so not getting this huh I dont think I will ever get this it is so hard :(

OpenStudy (anonymous):

5+x+x+12+x+2x+x+8+34+x+8

OpenStudy (anonymous):

the figure has different values for each side - add all up. i listed them above so now combine like terms

OpenStudy (anonymous):

u adding like terms?

OpenStudy (anonymous):

Like terms are the numbers right ?

OpenStudy (anonymous):

numbers are like AND the x's are the other term

OpenStudy (anonymous):

so you will have two terms one is a number the other will end with "x"

OpenStudy (anonymous):

so it would kind of be like 69x?

OpenStudy (anonymous):

7x + 67

OpenStudy (anonymous):

put a 1 in front of the x that do not have a # - it is implied
