The sum of two polynomials is why z squared minus 3z squared minus 4y +4 if one of the palm will normally else is y -4

Step-by-step explanation:

By definition, the sum is the result of the addition.

According to the information given in the exercise, the polynomial   is obtained by adding the polynomial   and another polynomial.

Then, you can find the other polynomial by subtracting   from :

So, the steps are:

1. You must distribute the negative sign:

2. Finally, you need to add the like terms:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
