(2x + 5) (2x -3) AREA = LENGTH X WIDTH AREA = 6-A)A rectangle has a length of 2x + 5 and a width of 2x -3. Which expression describes the area of the rectangle? AREA = LENGTH X WIDTH (2x + 5) (2x -3) AREA = WE USE A TI-82 TO ANSWER THIS QUESTION. 1)put the expression for the area in Y1 and the One you want to check in Y2. Checking D: You can enter all the answer choices and compare the columns Y1 to Y6 to find the answer! 2)Press 2nd GRAPH. If the numbers in Y1 and Y2 columns are exactly the same, then the expression you put in Y2 is equivalent to the one you put in Y1. Do this until you find the answer. D is the answer because the numbers in these columns are exactly the same! OBJECTIVE 6

The length of this side is: The length of this side is: { The length of this side is: X + X + 1 = 2X + 1 USE THE KEY TO FIND THE LENGTHS OF THE SIDES! x 1 -1 { The length of this side is: X + -1 + -1 = X – 2 The area of the model is the product of these expressions. So, the answer is D: = NOTE: WE COULD ANSWER THIS PROBLEM USING A TI-82 AS WE DID FOR THE PREVIOUS PROBLEM! OBJECTIVE 6
