PLEASE HELP ME! In the last week, Daniela has played 10 tennis matches. She remembers that her opponent had won 1 set in 4 of the matches and her opponent was expected to win a total of 6 sets over the course of 5 matches.

The opponent won 2 sets in 4 matches, 1 set in 4 matches, and 0 sets in 2 matches.

Step-by-step explanation:

Given that in the last week, Daniela has played 10 tennis matches, and she remembers that her opponent had won 1 set in 4 of the matches and her opponent was expected to win a total of 6 sets over the course of 5 matches, but she Can't remember how many times her opponent won 0 or 2 sets, knowing that in total he played 10 games, to determine the number of times his opponent obtained these results, the following calculation must be performed:

5 matches = 6 sets

10 matches = 12 sets

10 - 4 = 6

12 - 4 = 8

8/2 = 4

Therefore, the opponent won 2 sets in 4 matches, 1 set in 4 matches, and 0 sets in 2 matches.

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.
