Answer:
This means that each side of the rectangle measures 2x = x + x, and we get the coefficient 4 after calculating the area of the rectangle, (side * side) = 2x * 2x = 4x².
Step-by-step explanation:
The coefficient 4 for this case is a multiplicative factor, that is, the constant number that is found by multiplying the variable x².
This means that each side of the rectangle measures 2x = x + x, and we get 4 after calculating the area of the rectangle, (side * side) = 2x * 2x = 4x²
