Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.

Using that rule, we can see that x+5 is really x-(-5) so k = -5. 

Therefore,

p(k) = 0
p(-5) = 0

so the answer is choice D.

six friends are going to the state fair.The cost of one admission is $9.50, and the cost for one ride on the Ferris wheel is $1.
larisa86 [58]

We are given

total number of friends =6

the cost of one admission is $9.50

now, we can find total cost for admission

total cost for admission= total number of friends*cost of one admission

total cost for admission=6*9.50

we are given

cost for one ride on the Ferris wheel is $1.50

now, we can find total cost for Ferris wheel ride

total cost for Ferris wheel ride= total number of friends*cost of one ride

total cost for Ferris wheel ride=6*1.50

now, we can find total cost

total cost =total cost for admission+total cost for Ferris wheel ride

total cost=6*9.50+6*1.50

now, we can solve it

total cost=6(9.50+1.50)

total cost=6*11

total cost=66

so, the total cost is $66...........Answer
