Define x :
----------------------------------------------------------
Let one of the number be x. The other number is x + 2.
----------------------------------------------------------
Construction Equation :
----------------------------------------------------------
The sum of the square of the two number is 202.
![x^2 + (x+2)^2 = 202](https://tex.z-dn.net/?f=x%5E2%20%2B%20%28x%2B2%29%5E2%20%3D%20202)
----------------------------------------------------------
Solve for x :
----------------------------------------------------------
![x^2 + (x+2)^2 = 202](https://tex.z-dn.net/?f=x%5E2%20%2B%20%28x%2B2%29%5E2%20%3D%20202)
![x^2 + x^2 + 4x + 4 = 202](https://tex.z-dn.net/?f=x%5E2%20%2B%20x%5E2%20%2B%204x%20%2B%204%20%3D%20202)
![2x^2 + 4x - 198 = 0](https://tex.z-dn.net/?f=2x%5E2%20%2B%204x%20-%20198%20%3D%200)
![x^2 + 2x - 99 = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%202x%20-%2099%20%3D%200)
![(x+11)(x-9) =0](https://tex.z-dn.net/?f=%20%28x%2B11%29%28x-9%29%20%3D0)
![(x+11)= 0 \ \ or \ \ (x-9) =0](https://tex.z-dn.net/?f=%20%28x%2B11%29%3D%200%20%5C%20%5C%20or%20%5C%20%5C%20%28x-9%29%20%3D0)
![x = - 11 \ or \ x = 9](https://tex.z-dn.net/?f=x%20%3D%20-%2011%20%5C%20or%20%5C%20%20x%20%3D%209%20)
x = -11 is rejected, since it only want positive integer.
----------------------------------------------------------
Find the two numbers :
----------------------------------------------------------
x = 9.
x + 3 = 11
----------------------------------------------------------
Answer: The numbers are 9 and 11.----------------------------------------------------------
Answer: 12
Step-by-step explanation:
this is a right angled triangle so you use the pythagorean theory
which is a^2 + b^2 = c^2
you have c and b already. c is the hypotenuse.
a^2 + 16^2 = 20^2
a^2 + 256 = 400
a^2 = 400 - 256
a^2 = 144
then you square root 144 and get..
a = 12
Answer: The number is 46.3 repeating
Step-by-step explanation:
273 = 6x + 5
+ 5 = 6x
278 = 6x
----- = ---- = 46.3 repeating
6 = 6
Hope this helps :)
