The diagram shows the first 10 sides of a spiral pattern. It also gives the lengths, in cm, of the first 5 sides.

The lengths, in cm, of the sides of the spiral form a sequence.
Find an expression in terms of n for the length, in cm, of the nth side.​

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9
