Answer 2

Answer:

z = 10

Step-by-step explanation:

Step 1:  Make an expression

P = 2l + 2w

Step 2:  Distribute

184 = 2(5z + 2) + 2(4z)

184 = (2 * 5z) + (2 * 2) + 8z

184 = 10z + 4 + 8z

184 = 18z + 4

Step 3:  Subtract 4 from both sides

184 - 4 = 18z + 4 - 4

180 = 18z

Step 4:  Divide both sides by 18

180 / 18 = 18z / 18

10 = z

Answer:  z = 10
