2x = x/2 - 6.....multiply both sides by 2
4x = x - 12
4x - x = -12
3x = -12
x = -12/3
x = -4
3x = 12......3(-4) = 12.....-12 = 12...false......so 3x = 12 is not true because x = -4
F(x) = mx + b represent the straight line. If m ≠ 0 then the domain and the range of that function are real number.
The answer is $23.15 an hour, hope this helps!
Answer:

The dimension of the garden is 52.5ft by 43.5ft
Step-by-step explanation:
Given
The shape above
Required
Determine PQ
Determine dimension of the garden
Calculating Length PQ
Represent the length of the inner rectangle as L
Represent the width of the inner rectangle as W


The distance between the inner rectangle and the outer triangle is 4ft
This implies that;

Substitute
for 


Also;

Substitute
for 

Calculating The Dimension of The Garden
First, we need to determine the Area of the inner rectangle

Recall that
and 
So;

For the bigger rectangle

Recall that
and 
So;

Given that the Area of the walkway is 
This implies that

Substitute
and 

Open All Brackets


Collect Like Terms


Divide both sides by 8



Since the dimensions of the garden is
and 
<em>Substitute 43.5 for x in both cases</em>


<em>Hence, the dimension of the garden is 52.5ft by 43.5ft</em>
