@perdomo.arturo , if it helps, you can group the ones that are alike, like the "x"s and the non"x"s.

Answer 3

7x + 5x + 2x combine like terms

@perdomo.arturo

Answer 24

in the front with the other 2 and 5

Answer 25

So is the answer
2*5*x^4^+^1*2y^3^+^2
2*5*x^5*2y^5
10x^7y^5

Answer 26

@perdomo.arturo

Answer 27

The two you put in there should be in the front because it is a coefficient. Meaning it belongs in front of the variable not the exponent.

Answer 28

So what would the steps look like?
