1 answer:

5 0

P = 2l + 2w
P = 2(x + 3) + 2(7)
P = 2(x) + 2(3) + 14
P = 2x + 6 + 14
P = 2x + 20

A = lw
A= 7(x + 3)
A = 7(x) + 7(3)
A = 7x + 21

7400 dollars is placed in an account with an annual interest

Anastasy [175]

Answer:

Step-by-step explanation:

We have the following equation for compounding annual interest

AV=PV(1+i)ⁿ

We have

19200=7400(1+.06)ⁿ

Solve for n

divide both sides by 7400

2.594=(1.06)ⁿ

then use the following rule for exponents

$x^y=z\\log_xz=y$

which means that

$log_{1.06}2.594=n$

Solve and get

16.362

which rounds to 17
