Which equation would be used in proving that the diagonals of parallelogram abcd bisect each other? a) (3-1)2 + (2-0)2 = (1-3)2 + (0+4)2 b) (3+1)2 + (2+0)2 = (1+3)2 + (0-4)2 c) (-1-1)2 + (4-0)2 = (1-3)2 + (0+4)2 d) (-1+1)2 + (4+0)2 = (1+3)2 + (0-4)2

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
