Step-by-step explanation:

The domain of the rational expression is when the denominator is defined. (non-zero)

When the denominator is 0,

4x² - 4 = 0.

=> x² - 1 = 0, (x + 1)(x - 1) = 0, x = -1 or x = 1.

Hence the answer is all real numbers except x = -1 and x = 1.

billy is creating a circular garden divided into 8 equal sections. The diameter of the garden is 12 feet. what is the area, in s

xxTIMURxx [149]

Area=πr^2

find the area then divide by 8

we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
