Rectangular pyramid and triangular pyramid.
Answer:
12
Step-by-step explanation:
x^2 - a
If a is a perfect square we could factor
x^2 - b^2 = (x-b)(x+b)
So a cannot be 36,49,81 since they are perfect squares
a must be 12
For a square and rectangle it is Area=length*width
First I will find the tip and then I will add that to the total and THEN I will add my sales tax to find 6% you have to multiply by 0.06. to find 15% you have to multiply by 0.15
0.06 * 29.85 = 1.79
29.85 + 1.79 = 31.64
0.15 * 31.64 = 4.74
31.64 + 4.74 = $36.38
