A team won 8 games and lost 5.
What’s the Fraction of the games lost?

5/13

Step-by-step explantion:

You already know that they lost 5 games witch is the numerator. Then you add all the games to get the denominator. 8 + 5 = 13

So the answer is 5/13

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.
