Answer:
x = 9
Perimeter = 74
Area = 342
Step-by-step explanation:
First, find x. to do so, set your formula up as
18 = 8x - 54
18 + 54 = 8x
72 = 8x
72/8 = x
9 = x
Now that you have x, find your missing side
2x + 1 = y, x
2 * 9 + = y
19 = y
Your perimeter is P = 2(l+W)
P = 2(18 * 19)
P = 74
Your area is A = wl
A = 19 * 18
A = 342
Answer:
the third one because if u look at the picture u can see that that's what is haloing
Given:
The principal = $ 4000
The rate of interest = 22 %
To find the loan amount a) after 1 year and b) after 3 years.
Formula
Loan amount is

where,
A be the loan amount
P be the principal
r be the rate of interest and
t be the time.
Now,
a) Taking, P = 4000, r = 22, t = 1 we get,

or, 
Again,
b) Taking, P = 4000, r = 22 and t = 4 w eget,


Hence,
a) The amount of loan after 1 year is $ 4880
and b) The amount of loan after 4 year is $ 7263.39.
