The ratio of the number of Noah's stickers to the number of Jackson's stickers was 12:7. After Noah bought another 28 stickers and Jackson gave away 32 stickers, 5/7 of Jackson's stickers were left. A) How many more stickers did Noah have than Jackson in the beginning?

B) Find the new ratio of the number of Noah's stickers to the number of Jackson's stickers.

Please solve algebraically

a negative exponent is translated as follows:

so, we have

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.
