Question: 1 The product of two positive numbers is 15876 and the large one is 9 times the other. Find the numbers.
Question:2
Th sum of the squares of two positive whole numbers is 794. If one of the numbers is 13 , find the other.
Answered by Damon
x y = 15876
y = 9 x
so
9 x^2 = 15876
x^2 = 1764
x = 42
===================
169 + x^2 = 794
x^2 = 625
x = 25

1 .

a = first number

b = second number


The large one is 9 times the other.

This mean :

b = 9 a


a * b = 15876

a * 9 a = 15876

9 a ^ 2 = 15876 Divide both sides by 9

a ^ 2 = 15876 / 9

a ^ 2 = 1764

a = sqroot ( 1764 )

a = 42

b = 9 a = 9 * 42 = 3789


2.

a = first number

b = second number ( In this case b = 13 )


The sum of the squares of two positive whole numbers is 794.

This mean :

a ^ 2 + b ^ 2 = 794

a ^ 2 + 13 ^ 2 = 794

a ^ 2 + 169 = 794 Subtract 169 to both sides,

a ^ 2 + 169 - 169 = 794 - 169

a ^ 2 = 625

a = sqroot ( 625 ) = 25
