Rectangle ABCD has a length represented by the expression 2x – 3, and a width represented by the expression 4x + 5. Rectangle PQRS has a length represented by the expression x – 1, and a width represented by the expression 3x + 2. Which Expression can be used to represent the difference in the perimeter of Rectangle ABCD and Rectangle PQRS?
a) 2x + 1
b) 4x + 2
c) 4x + 6
d) 20x + 6
Answer:
b) 4x + 2
Step-by-step explanation:
The Formula for the Perimeter of a Rectangle = 2(L + W)
= 2L + 2W
Hence:
For rectangle ABCD
Length = 2x - 3
Width = 4x + 5
Hence, the Perimeter is :
P = 2L + 2W
P = 2(2x - 3) + 2(4x + 5)
P = 4x - 6 + 8x + 10
P = 4x + 8x -6 + 10
P = 12x + 4
For Rectangle PQRS
Length = x - 1
Width = 3x + 2
Hence, the Perimeter is :
P = 2L + 2W
P = 2(x - 1) + 2(3x + 2)
P = 2x - 2 + 6x + 4
P = 2x + 6x - 2 + 4
P = 8x + 2
The Expression that can be used to represent the difference in the perimeter of Rectangle ABCD and Rectangle PQRS is
Perimeter of Rectangle ABCD - Perimeter of Rectangle PQRS
(12x + 4) - (8x + 2)
12x + 4 - 8x - 2
12x - 8x +4 -2
4x + 2
Option b) 4x + 2 is the correct option.

Answer:
a.
b. $0.15 per can of pineapple
Step-by-step explanation:
a. 1. Here we need to make a variable () that represents the unknown cost of one single can of pineapple, then multiply by the total number of cans, which we are told is 44.
2. The second term is the cost of the 11 bottes of mayonnaise, which we know to be $2.89. We add this to the first term.
3. We know that the total of these two numbers should be equal to the total amount of money that Tom spent. This number will be the amount he gave the cashier ($10) MINUS the change the cashier gave back to him ($0.35)
4. Now that we have formed an equation, we just need to solve for .
Equation
Simplify parentheses on the right and subtract 2.89 from both sides.
Simplify on the right side again to find 6.76, then divide both sides by 44.
Simplify and give this value units ($) to find your final answer to question b.
