Answer:

CD = 38

Step-by-step explanation:

Since AB = 3x + 2, CD = 3x + 2

To solve for the length of CD, we'll need to solve for x first by using the perimeter formula

Solving for x...

(3x+2)+(3x+2)+2x+2x=124

3x + 3x + 2x + 2x = 120

10x=120

x=\frac{120}{10}

x=12

Now that we know what x equals, plug in x into the expression of side CD

CD = 3x + 2

CD = 3(12) + 2

CD = 36 + 2

CD = 38

Therefore, the length of side CD = 38

-------------------------------------------------------

Check:

AB = CD | BC = DA

38 + 38 for AB and CD

BC + DA = 2x + 2x

BC + DA = 2(12) + 2(12)

BC + DA = 24 + 24

BC + DA = 48

38 + 38 + 48 = perimeter

perimeter = 124

Ms. Wendie puts 4 chocolate candies in a bag to give each of her students on the first day of class. She puts a total of 76 choc
Alchen [17]
This scenario is all about creating equal groups of 4 candies.  Because we know the total number of candies that were used, the 4 is a part and we are missing the other part(groups).  We can think of it as how many groups of 4 will result in 76.  This is shown in Choice A.
