Billy Found The Slope of the line through the points (2,5) and (-2, -5) using the equation shown in the picture below. What mistake did he make?

What is the value of x in the diagram below?

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

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?
