Ben and jerry’s ice cream company estimates that for every 32 people that they serve their delicious ice cream to, they need to make 128 ounces of ice cream. how many people can they serve if they make 704 ounces of ice cream? set up a proportion and solve.

The first part of the proportion would be the known values of 32 people to 128 ounces.

The second part of the proportion is X ( the number of people) for 704 ounces.

This is written as 32/128 = X/704

To solve for X Cross multiply:

32 * 704 = 128x

Simplify:

22528 = 128x

Solve for X by dividing both sides by 128:

x = 22528 / 128

x = 176 people

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.
