Use your knowledge of squares and cubes to solve the equations below. Show your work for each question below. Be sure to check if it is or is not a perfect square or cube. x² = 100

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
