9. find x (click to see photo)

8 squared=(x+12)x

8 squared = x squared + 12x

52 = x squared

So x= the square root of 52

Step-by-step explanation:

The given expression is

2 1/3-1 2/3

These are mixed fractions. It has whole numbers and proper fractions.

We would start by subtracting the proper fractions. Both proper fractions have the same denominators. It becomes

1/3 - 2/3

The issue here is that 1 s lesser than 2. Subtracting 2 from 1 would result in a negative number. So we would borrow from the whole number, 2

The whole number, 2 can be expressed as (1 + 1). 1 whole represents 3. So we add 3 to the 1 in the numerator. The fraction becomes 1 (3+1)/3 = 1 4/3

The expression becomes

1 4/3 - 2/3

Subtracting the fractions, it becomes

4/3 - 2/3 = 2/3

Subtracting the whole numbers, it becomes. 1 - 0 = 1

The result becomes

1 2/3
