Question

Combine the like terms to simplify the expression:

4 + 7xy^2 + 5y^3 + 10x –4xy^2 – 8x – 4y^3 + 9

A.
y^3 + 3xy^2 + 2x + 13

B.
y^3 – 3xy^2 + 2x + 9

C.
y^6 + 3x^2y^2 + 10x + 13

D.
y^3 + 3xy^2 + 10x + 13

Answer 1

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

Answer 2

ok so the answer is c?

Answer 3

right???

Answer 4

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

Answer 5

You aren't adding the exponents, so for example x^2 + 4x^2 would just be 5x^2

Answer 6

oh

Answer 7

so its a or b right????

Answer 8

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

Answer 9

5y^3 not 57^3 lol

Answer 10
