Answer:
x =
Step-by-step explanation:
![\frac{3}{8}-x=[tex]\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D-x%3D%5Btex%5D%5Cfrac%7B1%7D%7B4%7D)
⇒ Minus 
from both sides
- x =
⇒ Multiply both sides by -1 to get rid of negative
x =
The sum of the area of these three rectangles will be 3x² + 20x.
<h3>What is the area of the rectangle?</h3>
Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The lengths and the widths of the following three rectangles are labeled.
The area of the first rectangle will be
A₁ = x · x
A₁ = x² square units
The area of the second rectangle will be
A₂ = 20 · x
A₂ = 20x
The area of the third rectangle will be
A₃ = 2x · x
A₃ = 2x²
Then the sum of the area of these three rectangles will be
A = A₁ + A₂ + A₃
A = x² + 20x + 2x²
A = 3x² + 20x
Thus, the sum of the area of these three rectangles will be 3x² + 20x.
