Answer:
2/3
Step-by-step explanation:
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
To help in the future, you can follow the equation
Whole * Percent = whole
In this case, the whole is 48 and the percent is 5/8
48 / 5/8 = 30
It would be 5 because 4/5 is 5
