1 answer:
Answer:
68 inches
Step-by-step explanation:
P = 2 (L + W)
P = 2(4x+5 + 4x+5)
P = 2(8x + 10)
P = 16x + 20
If x= 3
P = 16(3) + 20
P = 48 + 20
P = 68 inches

Answer by JKismyhusbandbae:
1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630
2. Balance after 1 year with compounded interest = P ( 1 +
= 600 ( 1 + = 600 (1.0511) = $630.66 = approx. $630
2 years is the same as 24 months, so the equation would be: 685 = 24x + 85, where x is the monthly fee. 600 = 24x 600/24 = x x = 25 The monthly fee is $25.
