In science class, the girl to boy ratio is 3 to 7, if there are 50 students total in class, how many are boys

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.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer is 1

step-by-step explanation:

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
