<h3>
Answer: Choice A) 50</h3>
For two numbers x and y, the geometric mean is G = sqrt(x*y)
In this case, x = 25 and y = 100, so
G = sqrt(x*y)
G = sqrt(25*100)
G = sqrt(2500)
G = 50
5(4x-3)^2 - 3
5(16x^2 - 2(3)(4x) + 9) -3
5(16x^2 - 24x + 9) -3
80x^2 - 120x + 45 - 3
80x^2 - 120x + 42
80(0)^2 - 120(0) + 42
42
Since there is a sales tax of 6% which was equal to $820
Let the value be = x
6% of x = 820
(6/100)x = 820
0.06x = 820
x = 820/0.06
x = 13666.67
Value to the nearest dollar ≈ $13 666.67
Answer:
Aman's age = 20, Arun's age = 28
Step-by-step explanation:
Let 
= Aman's age
Let 
= Arun's age
- - - -
(Sum of their age is 56 after 4 years in the future)
(Ages are in the ratio 5:7)
Now, we can use substitution to find for Arun's age:
∴ Arun is 
To find for Aman's age, we can use substitution:
∴ Aman is 20
Hope this helps :)
