A quartic polynomial function f has a leading coefficient of 4 and a constant term of -11. When added, the coefficient of the x^3 term and the coefficient of the x^2 term is equal to 7. f has a root at x = 1, and when x = -1, f is equal to -18.

the answer would be c

you are having disney spells!

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
