Translate the verbal expression describing the length into a mathematical expression.
C
Practice makes perfect
Let's call the rectangle's width x. To determine the length, we have to translate the verbal description of it into a mathematical description.
Sentence:
The length is three units
shorter than twice its width [1em]
↓ [0.4em]
Equation:
l = 2 x - 3
Once we have expressions for both its dimensions, we can create an illustration of the rectangle that includes them.
The area of a rectangle is calculated by multiplying its width and length.
Area: x(2x-3)=2x^2-3x
This matches option C.
