Which of the following options have the same value as 20% of 45 choose 3answers

9

Step-by-step explanation:

Seeing as there really isn't a choice to choose between 3 answers, I'll do the math manually and hope it's right.

You need to convert 20% to a decimal. Because 20% is really 20.00, you're going to take the decimal point and move it 2 places to the left --> .20

Because "of" signifies multiplication, you're going to multiply .20 by 45.

So, .2 x 45 = 9

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.
