The sum of the interior angles of a triangle is 180 degrees, of a quadrilateral is 360 degrees, and of a pentagon is 540 degrees. assuming this pattern continues, find a sum of the interior angles of a dodecagon

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

The difference between two numbers is one. three times the larger number minus two times the smaller number is 9. what are the two numbers

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.
