1st photo is simplifying the entire account.
2nd photo is how i simplified the x^2 + 9x + 18 equation into (x+3).(x+6) .
3rd photo is the remaining part of the 2nd photo.
Answer: 2nd option = (x+6)(x+5)
3 to the second power would be 9 .
3 to the fifth power would be 243 .
0.009 is the answer. You have to move the decimal to the left 3 places because there are 3 zeroes in 1000.
For example:
9/100=0.09 (You move the decimal 2 places because there are 2 zeroes in 100)
9/10000=0.0009
9/10=0.9

Solution:
Given equation is
.
To solve the equation by step by step.
Step 1: Given

Step 2: Combine like terms together.
Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

Step 3: Subtract the fractions in the left side.

⇒ 
Step 4: Divide both side of the equation by 3, we get


Hence, the answer is
.
