Samir goes to a farmers market to buy some fruit. He fills a large bag with 21kg of apples. He realizes that he cannot carry this weight, so puts some of the apples into a smaller bag. The weight of the apples in the large bag is 9kg larger than the smaller bag.(a) What is the weight of the smaller bag?

i’m sorry but i didn’t remenber the question

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.
