A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B.
The remaining students in the class did not vote.

Which expression gives the percent of voters who voted for Candidate A?

Bottom right

Step-by-step explanation:

yes.

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.

slope is 35 and 20 miles is the y-intercept.
