What is the degree of x^5+1-3x^9-2x

this polynomial has a degree of 9.

The degree of a polynomial is the highest power of the unknown with a non-zero coeficient.

This expresion has unknown x raised to the 5th, 4th, 9th and 1st power

(x=x1)

with coeficients of : 1,-3,+3 and -2 respectively. So the highest power (i.e. the degree of the polynomial) is 9.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
