Answer:
x = 4±sqrt(19)
Step-by-step explanation:
Assuming you meant x^2 -8x = 3
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16= 3+16
The number inside the square term is the coefficient divided by 2
(x-4)^2=19
Take the square root of each side
sqrt((x-4)^2=±sqrt(19)
x-4 = ±sqrt(19)
Add 4 to each side
x-4+4 = 4±sqrt(19)
x = 4±sqrt(19)
Answer:hi
Step-by-step explanation:

One fifth of 25 people is 5 people. 25 - 5 = 20.
Y = (5.2)^x is exponential growth.
The exponential equation is y = a * b^x
If b > 1 then the function is exponential growth.
If 0 < b < 1 then the function is exponential decay.
