Two math classes took the same quiz.The scores of 10 randomly selected students from each class are listed below based on the medians of the scores for each class, what inference would you make about the quiz scores of all the students in class A compared to all the students in class B?

The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n  +7

Step-by-step explanation:

The given expression is (m + n + 3) + (m + n + 4)

we need  to find the sum of this expression

so, first we add the similar terms

m + n + 3 + m + n + 4

first write the like term together and then constant,

⇒ m + m + n + n +3 + 4

⇒ 2m + 2n  +3 + 4

⇒ 2m + 2n  +7

Therefore, The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n  +7
