OpenStudy (lgbasallote):

with what?

OpenStudy (anonymous):

Joy is training for a triathlon. She runs a distance of 2x miles, cycles a distance of (x2 + 7) miles, and swims a distance of (x - 2) miles. Which simplified expression is equivalent to the total distance, in miles, Joy covers?

OpenStudy (anonymous):

can you be more specific in your notation

OpenStudy (anonymous):

so how much cyclicing does she do 2x +7 ?

OpenStudy (anonymous):

idk thats just the question they gave me.

OpenStudy (anonymous):

so x2 ? i am just going to assume it means 2x ok?

OpenStudy (anonymous):

not x^2

OpenStudy (anonymous):

okayy

OpenStudy (anonymous):

do you want the answers that it gave me ?

OpenStudy (anonymous):

alright so for this the total distance is just adding all the distance she covered so we get 2x + (2x+7) + (x-2) = add all the like terms we get 2x +2x +x + 7 -2 = 5x +5 :)

OpenStudy (anonymous):

is that the answer?

OpenStudy (anonymous):

these are the answers x2 + 3x + 5 x2 + 3x + 9 3x2 + 5 3x2 + 9

OpenStudy (anonymous):

i am not understanding what is x2 :s

OpenStudy (anonymous):

its x^2

OpenStudy (anonymous):

o alright so ignore my first answer then I asked you but its okay i will do it again

OpenStudy (anonymous):

alright so for this the total distance is just adding all the distance she covered so we get 2x + (x^2+7) + (x-2) = add all the like terms we get 2x +x^2 +x + 7 -2 = x^2 + 3x +5 :)
