Calcula las operaciones que se indican entre los polinomios si se sabe que: -P (y) = 7y3 + 5y2 - y + 2
-Q (y) = 10y - 5 - 6y4 - 3y2
-Z (y) =20y2 - 15 - 8y4 + 7y
-A) P(y) + Q(y)
-B) Z(y) - P(y)
-C) Z(y) + Q(y)

the answer is two. hope this !

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

48+y= ?

the y is the variable and the ? could also be a variable
