Question

Combine like terms to simplify the expression:

7x + 3y – 2 + 6x + 1 + y2

A.
y2 + 3y + 13x – 1

B.
2y3 + 13x – 1

C.
3y3 + 13x2 + 1

D.
y2 + 3y + 13x2 + 1

Answer 1

The x's go with the x's. The y's go with the y's. The y^2s go with the y^2s. Don't add up different variables. What's your best attempt?

Answer 2

I think C or D

Answer 3

No. You can't add different variables. y + y^2 DOES NOT equal y^3.

Answer 4

so its nor D eiether

Answer 5

No, but don't guess. Do the math. There is only one y term. There is one y^2 term. There are two x terms though, you add those together. And there are two constants (numbers), you add those together.

Answer 6

cause if it cant equal y^3 it has to be D or A

Answer 7

well I'm thinking A if I'm doing the math right but I suck at algebra I'd be better at it if algebra didn't hook up with the alphabet

Answer 8

Well, it does hook up with the alphabet. And everything after algebra does. Get used to it. It's A.
