Ari decides to run 8.5 kilometers this weekend. He jogs 8.9 laps around the running track on Saturday. How many more kilometers does he need to jog on Sunday? Venue Kilometers Pool 0.05 Running Track 0.4 Which equation shows the first step in solving this problem? y = 8.9 times 0.4 y = 8.5 times 0.4 y = 8.5 divided by 0.4 y = 8.9 divided by 0.4

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.

answer: 1+1

step-by-step explanation: 1+1 is at least 2

the answer is 9 because the question is telling how much it be together.
