If x is to 9 as 8 is to 12, then x is equal to

Step-by-step explanation:

This is basically just a ratio in disguise. Ratios can be represented as fractions, and we can write these ratios to be equal to each other.

We can solve for x using the cross products property:

Hope this helped!

x=6

Step-by-step explanation:

We can write ratios to solve

x          8

=

9           12

Using cross products

12x = 8*9

12x = 72

Divide by 12

x = 72/12

x =6

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.

ou would have 12 of each
