15. Evaluate the polynomial x3 + x2 + x + 3 at the given value of x = -2
a. 3 b.-3
C. 17
d.-17
Help pls

   B   (-3)

Step-by-step explanation:

To evaluate the polynomial, we have to substitute x for the givwn value of x = -2.

polynomial at x = -2   :  (-2)³  +  (-2)²   +  (-2)  + 3  =  -8  +  4  -  2  +  3

                                                                               =  - 3

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
