Imagine working with a younger sibling or student who is having trouble with the 9 times table. Create an algorithm to help the
student learn how to do this easily. You may need to use outside resources to help you. If you do, make sure to document where you retrieved those sources. Note: Remember an algorithm is a description on how to perform a process. Try using numbered steps or bullet points to list instructions. Your algorithm must be able to be easily followed by others so they get the same results as you did. For example, if you made an algorithm on how to make a chocolate cake, you'd want others to be able to follow it so that their cake ended up tasting as delicious as yours!

Answer:
1. x = 12
2. 3∛4 feet.
Step-by-step explanation:
1. We are given the equation of x as and we have to find the extraneous solution of the equation.
Now, ............. (1)
⇒
Squaring both sides we get,
⇒ x - 3 = 81 - 18x + x²
⇒ x² - 19x + 84 = 0
⇒ x² - 12x - 7x + 84 = 0
⇒ (x - 12)(x - 7) = 0
⇒ x = 12 or 7.
Now, putting x = 12 in the equation (1) we get,
Again, putting x = 7 in the equation (1) we get,
Therefore, x = 12 is an extraneous solution of this equation. (Answer)
2. The volume of a cube with side lengths a ft. is given to be 108 ft³.
So, a³ = 108
⇒ a = 3∛4 feet.
Therefore, the length of the sides of the cube are each 3∛4 feet. (Answer)
