It looks intimidating but it's really easy. Just add up the like terms. e.g. 7xy^2 is a like term with -4xy^2
ok so the answer is c?
No, add 5y^3 to -4y^3 then add 7xy^2 to -4xy^2 then add 10x to -8x and then add 9 to 4
You aren't adding the exponents, so for example x^2 + 4x^2 would just be 5x^2
so its a or b right????
You shouldn't have to guess. 57^3 -4y^3 is y^3 7xy^2 -4xy^2 is 3xy^2 10x-8x is 2x and 4+9 is 13
5y^3 not 57^3 lol
aaahhh ok so its d right?????
No, it's a.... D:
awww ok but thx for helping me you helped alot :D
