Ten less than five times a number is less than six times the number decreased by eight

5n-10 < 6n-8

n - is the variable that's stands for the unspecified number

step 1. ten is less than 5 times a number

step 2. LESS THAN SIGN :)

step 3. six times the number decreased by 8

*tip: sometimes it helps to break the problem into parts and reading it backwards*

I hope this helps. :)

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.
