The solutions of the equation are -12 and 16
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then
∵ 2Ix - 2I - 8 = 20
- At first add 8 to both sides
∴ 2Ix - 2I = 28
- Then divide both sides by 2
∴ Ix - 2I = 14
Now By using the notes above equate x - 2 by 14 and -14
∵ x - 2 = 14
- Add 2 to both sides
∴ x = 16
∵ x - 2 = -14
- Add 2 to both sides
∴ x = -12
The solutions of the equation are -12 and 16

Answer:
864 m²
Step-by-step explanation:
- First calculate the total area of the rectangular field 
The area of a rectangle is given by the product of the length and the width 
let A be the total area 
A = 100*120 
A = 12000 m² 
Calculate the area of the small rectangles 
- Let A' be the total area of the four small rectangles and A" the area of one small rectangle 
- A' = 4 A" 
- A' = 4 [( )*( )*( )] )]
- A' = 4*58*48
- A' = 11136 m² 
- Substract the A' from A to get the area of the road 
Let A"' be the area of the road 
A"' =A-A' 
A"' = 12000-11136
A"' = 864 m²
 
 
        
             
        
        
        
To find what profit they made, subtract what they earned from what they spent money on. 275-55=220. They made a total of $220 after paying for supplies. I hope this helps! :)
