Given f(x) = 2x + 1 and g(x) = 3x + 5, find h(x) = f(x) ∙ g(x).

h(x) = 5x + 6

h(x) = 6x2 + 13x + 5

h(x) = 6x2 + 7x + 5

h(x) = 10x + 12

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

What is the prime factorization of 230

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?
