Answer:
![(x^{2}-x-2)\ units^{2}](https://tex.z-dn.net/?f=%28x%5E%7B2%7D-x-2%29%5C%20units%5E%7B2%7D)
Step-by-step explanation:
step 1
Calculate the area of the shaded portion
![A1=(2x+3)(x+1)\\ \\A1=2x^{2}+2x+3x+3\\ \\A1=(2x^{2}+5x+3)\ units^{2}](https://tex.z-dn.net/?f=A1%3D%282x%2B3%29%28x%2B1%29%5C%5C%20%5C%5CA1%3D2x%5E%7B2%7D%2B2x%2B3x%2B3%5C%5C%20%5C%5CA1%3D%282x%5E%7B2%7D%2B5x%2B3%29%5C%20units%5E%7B2%7D)
step 2
Calculate the area of the unshaded portion
![A2=(x+5)(x+1)\\ \\A2=x^{2}+x+5x+5\\ \\A2=(x^{2}+6x+5)\ units^{2}](https://tex.z-dn.net/?f=A2%3D%28x%2B5%29%28x%2B1%29%5C%5C%20%5C%5CA2%3Dx%5E%7B2%7D%2Bx%2B5x%2B5%5C%5C%20%5C%5CA2%3D%28x%5E%7B2%7D%2B6x%2B5%29%5C%20units%5E%7B2%7D)
step 3
Find the difference of the areas
![A1-A2=(2x^{2}+5x+3)-(x^{2}+6x+5)=(x^{2}-x-2)\ units^{2}](https://tex.z-dn.net/?f=A1-A2%3D%282x%5E%7B2%7D%2B5x%2B3%29-%28x%5E%7B2%7D%2B6x%2B5%29%3D%28x%5E%7B2%7D-x-2%29%5C%20units%5E%7B2%7D)
Answer:
equation ---> 120+10(m)=150+4(m)
m= number of months
(By the way the answer would be 5 months)

Answer:
The answer is 181
Step-by-step explanation:
PEDMAS
1 x 1 + 9 x 20
1 x 1 = 1
1 + 9 x 20
9 x 20= 180
1+180
which equals 181
