(16 - 6) + f - 9 = 12

f = 11

Step-by-step explanation:

F=11

Step-by-step explanation:

parenthesis first

10+f-9=12

combine like terms

1+f=12

-1 from both sides to solve for f

f=12-1

f=11

Hope this helps have a great day

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

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.
