Please answer this question quick and right and with proof

b or c hope this helps

Step-by-step explanation:

c) 15 people

Step-by-step explanation:

9 1/2 = 19/2

19/2 and 3/5

find common denominators

95/10 and 6/10

95/6 = 15.833333

you cant serve 16 people equally so its 15 people with .83333 left if ice cream.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
