Answer:
Step-by-step explanation:
Alright, lets get started.
Area is given as 49 square inches.
The formula for area A = 
base is given as x
Height is given as x
Hence area is A
A = 
Multiplying 2 in both sides

Taking square root on both sides

hence the answer is x = 9.9 in : Answer
Hope it will help :)
You can make it easier by replacing x^n with another variable, factoring, then putting x^n back in the end.
Using exponent and algebra rules, rewrite x^2n - 2x^n + 1 as
(x^n)^2 - (2 x x^2) + 1
Then, let x^n = m.
m^2 - 2m + 1
Now factor that: (m - 1)^2
And now put x^n back: (x^n - 1)^2
Answer:
$25,193.17
Explanation:
Given:
• Principal Felipe borrowed, P=$8000
,
• Annual Interest Rate, r=16.5%=0.165
,
• Compounding Period, k=12 (Monthly)
,
• Time, t=7 years
We want to determine how much he will owe after 7 years.
In order to carry out this calculation, use the compound interest formula below:

Substitute the values defined above:

Finally, simplify and round to the nearest cent.

After 7 years, Felipe will owe $25,193.17.
72 divided by 6374 is equal to 0.0113

Answer:
Option C.
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
