Translate the following expression. One-fifth of the sum of b and 2 minus the product of 9 and r.

1/5*(b+2)-9*r) ( b+3-9r)/5

Step-by-step explanation:

1/5*((b+2)-9*r))

(my work below)

9r

b+3-9r/5

can't be simplified

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

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.
