The number is 470, 000

To explain further:
An example is
14,494 
To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: 
10, 000 = ten thousand 
4, 000 = thousands 
400 = hundreds 
90 = tens 
4 = ones 
Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.

Match each word problem to the equation that models it. tiles the sum of the squares of two positive integers is 394. if one int

Dovator [93]

Let
x--------> the larger integer
y-------> the smaller integer

we know that
x²+y²=394-----> equation 1
x=y+2-----> equation 2
substitute equation 2 in equation 1
[y+2]²+y²=394-----> y²+4y+4+y²=394
2y²+4y-390=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
y=13
x=y+2---> x=13+2---> x=15

the answer is
the numbers are 15 and 13
