Answer:
4 - ( 3x - 8 ) = 21 
break the bracket first ,it gives : 4 - 3x + 8 = 21 
12 - 3x = 21 
- 3x = 21 - 12 
- 3x = 9 
-x = 9/3 
-x = 3 
X = - 3
[ check if the answer is correct, put -3 instead of X in the above equation ! we get 4 - { 3(-3) - 8 } = 21 
4 - { - 9 - 8 } = 21 
4 - { - 17 } = 21 
break the bracket, minus and minus will multiply and will become plus , so we have 4 + 17 = 21 , hence 21 = 21 ! therefore X = -3

The figure is the combination of trapezoid and square. Then the area of the figure will be 39 square meters.
The complete question is attached below.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The figure is the combination of trapezoid and square.
Then the area of the geometry will be
Area = Area of trapezoid + Area of square
Area = 1/2 x (3 + 9) x 5 + 3 x 3
Area = 30 + 9
Area = 39 square meters

Answer:
A
Step-by-step explanation:
Given
 x - 4 = - 2 ( add 4 to both sides )
 x - 4 = - 2 ( add 4 to both sides )
 x = 2 ( multiply both sides by 6 to clear the fraction )
 x = 2 ( multiply both sides by 6 to clear the fraction )
5x = 12 ( divide both sides by 5 )
x =  = 2
 = 2  → A
 → A
