Is -0.3 a rational number? is 3.14144144414444... a rational number?
Ainat [17]

I will try to make this as simple as possible.

First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:

1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)

With that being said, let's begin.

First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing \frac{-3}{10} we have the equivalent of -0.3, so now we know it's a rational number.

As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:

-0.3 is a rational number, but 3.14144144414444 is not.

Hope this helped! c:

Solve this x2 – 8x + 15
STALIN [3.7K]

Answer:

x=5    x=3

Step-by-step explanation:

x^2 – 8x + 15

What two numbers multiply to 15 and add to -8

-5*-3 = 15

-5 +-3 = -8

(x-5) (x-3) =0

Using the zero product property

x-5 =0         x-3 =0

x=5                x=3
