For a project, you need to make three triangles out of cardboard. each triangle has a height of 5 inches and a base of 10 inches. which equation can you use to solve for the total amount of cardboard you will need? clear check 3·(12·5·10)= (12·5·10)÷3= (12·5·=3 =12·5·10

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?
