Determine if the expression represents a rational or irrational number. V 165
Rational
O Irrational

irrational

Step-by-step explanation:

it is a whole number but is it a perfect square number no so that is why it is irrational

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
