Answer:
-0.7
Step-by-step explanation:
-2n+1.8=3.2
-2n=3.2-1.8
-2n=1.4
n=1.4/-2
n=-0.7

Answer:
Please check the explanation.
Step-by-step explanation:
<u>Calculating the area of the outer rectangle:</u>
Given 
- The length outer rectangle = l = 3x - 1
- The width of outer rectangle = w = 5x + 2
Thus,
The area of the outer rectangle:
 
     
     
      
       
<u>Calculating the area of the inner rectangle:</u>
Given 
- The length inner rectangle = l = x + 7
- The width of inner rectangle = w = x
Thus,
The area of the outer rectangle:
A = wl
    = x(x+7)
    = x² + 7
<u>Calculating the area of the shaded region:</u>
As
The area of the outer rectangle = 15x² + x - 2
The area of the inner rectangle = x² + 7
- The area of the shaded region can be determined by subtracting the area of the inner rectangle from the area of the outer rectangle. 
Thus, 
shaded region Area = Outer Rectangle Area - Inner Rectangle Area
                                   = 15x² + x - 2 - (x² + 7)
                                    =  15x² + x - 2 - x² - 7
                                    = 14x² + x - 9
Therefore, the Area of the shaded region is: 14x² + x - 9
