Alana can complete 100 math facts in 5 minutes. How long does it take her to complete 1 math fact?

3 seconds

Step-by-step explanation:

Convert minutes to seconds: 5*60=300 seconds. 100 math facts in 300 seconds. 100/300=3. She solves a math question every 3 seconds (holy cr.ap that's fast)

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.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
