Area of a square = Length ^2

480    =   (x+4)^2

√480 = x + 4

21.9     = x  + 4

x          = 17.9

What is the result of 5/6 + 2/3
Goryan [66]
You can convert 2/3 into a fraction that makes adding a lot easier.

Since 3 times 2 is equal to 6, you can multiply the numerator and denominator of 2/3 by 2 to get 4/6.

From there, you add 4/6 + 5/6 to get 9/6.

Since both 9 and 6 are divisible by 3, you can simplify the fraction to 3/2.

Your final answer would be 3/2
Which can also be formatted as 1 1/2 or 1.5
