Read the screenshot and please explain

A, because the chart has a constant rate of 7 minutes per box. Multiply the 7 by 5 and you will get 35 minutes, and do the same with 1 and get 5 boxes. I hope this helps and I love your profile pic! I'm a fan of Danganronpa too!

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.
