Answer:
5/9, 2/7, 3/10 are all rational numbers
Step-by-step explanation:
Remember that all rational numbers are able to be written as a fraction or ratio of two integers.
Answer:
It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.

On a number line, that would translate to a number line with two dots on it, one at -3 and one at +3.
