(x - 4) + (2x - 7) = 3x - 11
You get that by:
Adding the x terms (one plus two) to get 3x; and adding the plain (non-x) numbers together. In this can both plain numbers are negative, so you get a negative of eleven, which is the sum of the absolute values 4 and 7.

What is the degree of the polynomial 2x7 plus 4 - 3x3 plus 5x8 - 4x?
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
