Introduction:

Extra Secret Special Hot BBQ RUB: This list constitutes the recipe in its original form and is not expanded to allow for use on more than one large size brisket or several steaks, burgers, etc., to keep the original recipe secret. Ingredients:  1 tbsp Dry Mustard  1 tsp Onion Powder  1 tsp “Special Ingredient”  1 tsp Garlic  1/8 tsp Cumin  2 tbsp “Secret Special Ingredient”  1 tbsp Season Salt  1 tbsp Black Pepper  1 tbsp “Super Secret Special Ingredient”  1 tbsp Course Pepper  1 tsp White Pepper

Using Polynomial Math to change recipe size: To increase recipe size, simply use math: A= First ingredient, B= Second Ingredient, C= Third ingredient, etc. Next you simply add an exponent to each letter to represent the increase, like A^2+B^2+C^2 to double the size, A^3+B^3+C^3 to triple the size, etc. This will allow you to make any size version of the original recipe. Hint: you can also make a smaller version by using fractions, for example 1/2A+1/2B+1/2C or 1/4A+1/4B+1/4C, etc.. Once you add up all of the parts you will have a copy of the original recipe in either a larger or smaller form for use on any size BBQ item. Keep in mind you portion sizes to ensure proper recipe change, tbsp versus tsp, etc., or your BBQ results may suffer and go up in smoke.

Beautiful flowerbed  After finally building your deck you decide you would like to add a flowerbed along the perimeter and need to know how much mulch to buy. Rather than trying to measure an awkward space you can use the measurement of your deck to get started.

Using Polynomial Math for your flowerbed  The deck is 15 feet long and 20 feet wide, and to find the perimeter you must take 2 x length + 2 x the width. Therefore P=2l + 2w or P= (2 x 15) + (2 x 20), now we need to add the additional two feet for the flowerbed so our new equation states P= (2l+4) +(2w)^2; our length will increase 4 feet total but our width will increase to twice as much. If you have yet to stain your deck the equation for area is A=length x width+ 3x the length for your railings or A= (l x w) + 3l
