Find the perimeter of rectange MNOP with vertices M (-2,5), N (-2, -4), O (3, -4), and P (3,5) Part B: Square ABCD has vertices A(-4.5, 4), B (3.5, 4), C (3.5, -4), and D (-4.5, -4). What is the area of Square ABCD?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false
