Area of the rectangle = 4x² + 12x + 8
Explanation:
Area of a rectangle = length * width
length = 4
width = x² + 3x + 2
Area of the rectangle = 4 (x² + 3x + 2)
Expand: Multiply the number outside(4) by each of the expression or number at the top of the table:
4(x²) = 4x²
4(3x) = 12x
4(2) = 8
An addition sign seperates each of the expression:
Area of the rectangle = 4x² + 12x + 8
