An architect is making a floor plan for a rectangular gymnasium. If the gymnasium is 80 feet long and 60 feet wide, what will the distance be between opposite corners.

The value √10 and √15 are plotted on the number line

65 8 7 4 5 6 8 4 3 2 1 9 5 6 4 2 1 6 5 1 5 1 3 2 3 5 multiply the third number in the first row by the seventh number in the third row. add this result to the fifth number in the second row. add to this total ten times the fourth number in the third row. subtract the eighth number in the first row from the result.

Solve: 3x+y=6 4x-2y=18 show all work !
