Find the value of c so that (x - 3) is a factor of the polynomial p(x). p(x) = x^4 - 3x^2 + - 2x + c
a) c = 48
b) c = 60
c) c = -48
d) c = -60

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

x/3-10=8

x/3=18

x=48
