In the figure, side AB is given by the expression 5x+5x+3, and side BC is 3x+92x−4. The simplified expression for the area of rectangle ABCD is ________ and the restriction on x is_____
We are asked to solve for the simplified expression of rectangle ABCD and the restriction on x. The solution is shown below: L = 3X + 92X -4 = 95X -4 W =5X + 5X +3 =10X +3
The formula is Area = L*W Area = (95x-4) * (10x +3) Area = 950x² + 285x - 40x -12 Area = 950x² + 245x -12 x should be greater than zero
