To find the area of this figure, there is two choices
1. cut it into 3 rectangles.
2.find the missing rectangle in the middle......
I likes 2 better $_$  :}
find the missing area in the middle, 12* 23 = 276
the area of the whole figure 31*69-276=1863m²
        
             
        
        
        
Answer:
x = -5
Step-by-step explanation:
to evaluate for x in this this question -5x-(8-x)=12
the firsst step, you would open the bracket with - then evaluate for the value of x
solution
-5x-(8-x)=12
-5x -8 + x = 12
combine the like terms
-5x + x = 12 + 8
-4x = 20
divide both sides by the coefficient of x
-4x/-4 = 20/-4
x = -5
 
        
             
        
        
        
Answer:
Step-by-step explanation:
- Let (applicable to all three lines below)
- Hard candy = x kg with price $1.60/kg
- Gummy worms = y kg with price $2.20/kg
- Total weight = 50 kg with mixed price $1.75/kg
<u>Required equations:</u>
- x + y = 50                        total weight
- 1.60x + 2.20y = 50*1.75      total price
=========================================
<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>
<u>Simplify the second equation and solve by substitution x = 50 - y:</u>
- 1.6(50 - y) + 2.2y = 87.5
- 80 - 1.6y +2.2y = 87.5
- 0.6y = 7.5
- y = 7.5/0.6
- y = 12.5
<u>Find the value of x:</u>
<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg
