Why is subtracting an expression similar to distributing a –1? A. You increase each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.

B. You multiply each term inside the parentheses by –1 in order to add each term, since subtraction is the multiplicative inverse.

C. You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the multiplicative inverse.

D. You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.

What set does not contain -3 the set of all real numbers the set of all integers the set of all whole numbers the set of all rational numbers

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?
