Answer:
156
Step-by-step explanation:
s8 = n/2 [2t + (n-1)(d)]
= 8/2 [2(2) + (8-1)(5)]
= 4 [4 + (7)(5)]
= 4 (4 + 35)
= 4 (39)
= 156

When adding/subtracting variables you can only add/subtract those variable that are of the same power....
3x^3-2x+8+2x^2+5x+x^3+2x^2-3x-3
(3x^3+x^3)+(2x^2+2x^2)+(-2x+5x-3x)+(8-3)
4x^3+4x^2+5
The term polynomial comes from the words poly- which means "many" and -nomial meaning "terms". In mathematics, a polynomial is an expression that consists of variables and coefficients wherein it only utilizes addition, subtraction, multiplication and a non-negative integer. In the given options above, the variable expression that is not a polynomial is option C. x^9+y^3.
