Is the order that I’m putting them in correct? If it is what are the answers to the others? It it’s wrong what is the correct order? Please help! Thanks! :) (These are PIECEWISE FUNCTIONS by the way)

When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Find two numbers if their sum is 91 and the ratio is 6: 7?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
