Turtles and tortoises have long life spans. A tortoise can live for 54,750 days. How many years can a tortoise live?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
