The sum of 3x^2 + x - 7 and x^2 + 10 can expressed as

4x^2 + x + 3

Step-by-step explanation:

Here, we want to find the sum of the two polynomials

That would be ;

3x^2 + x-7 and x^2 + 10

Adding means we are taking like terms together

That would be

3x^2 + x ^2 + x -7 + 10

= 4x^2 + x + 3

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set
