The perimeter of a square is 80 - 64y units. Which expression can be used to show the side length of one side of the square. A. 16(5-4y).Each side measures 5-4y units
B. 16y(5-4y) Each side measures 5-4 y units
C. 4(20-16y)Each side measures 20-16y units
D 4y(20-16)Each side measures 20-16 units

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
