Which expressions are solutions to the equation 2.4y = 13.75? Select all that apply. 2.4 : 13.75 13.75 2.4 13.75 : 2.4 13.75 -2.4 13.75 - 1.4?​

answer: i don't understand. what are the options

step-by-step explanation:

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.

24+x=y
