Last summer, at camp okey fun okey, the ratio of the number of boy campers to girl campers is 9: 6.if there is 225 campers, how many boy campers were there? how many girl campers?

  135 boys : 90 girls

Step-by-step explanation:

The sum of ratio units is 9+6 = 15. Then each ratio unit must stand for ...

  225/15 = 15 . . . campers

Multiply the ratio by 15 to find the numbers of interest.

  boys : girls = 9 : 6 = 135 : 90

There were 135 boy and 90 girl campers.

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.
