18. If the following fractions were converted to decimals, which one would result in a repeating decimal? A. 5/12
B. 1/9
c. 3/7
D. 3/4

Step-by-step explanation:

5/12=0.416666...

1/9=0.11111...

3/7=0.4285714285714...

3/4=0.75

A,B,C are repeating decimals,D is not .

if you select only one then B

46.2+112.3

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.
