Best ResponseYou've already chosen the best response.0constants: 4+9 = 13 xy^2: 74 = 3xy^2 y^3: 54 = y^3 x: 108 = 2x y3 + 3xy2 +2x +13 (answer B) am i right

Best ResponseYou've already chosen the best response.0Look at all the terms to see which terms happen more than once. The + or  sign in front of the term tells you whether it's positive or negative. Then add together all the sets of terms which are the same. Put the term with the highest exponent first, then put in the rest of the exponents in descending order. 4+9= 13 7xy2+(4xy2)= 3xy2 5y3+(4y3)= y3 10x+(8x)= 2x 13+3xy2+y3+2x y3+3xy2+2x+13
