$\sf \longmapsto\dfrac{ {x}^{2} - 9 }{ {x}^{2} - 3x}$

$\sf \longmapsto \dfrac{x + 3(x - 3)}{x(x - 3)}$

$\sf \longmapsto \: \dfrac{x + 3}{x}$

$\boxed{\sf \dfrac{x + 3}{x} }$

A quarter has a diameter of 2.4 m . what is it's circumference in cm

Vlad [161]

First lets convert the diameter to cm,
2.4 m equals 240 cm, that is by multiplying 2.4 times 100 because 1 meter has 100 cm
then we need to know how to calculate the circumference, and that is by multiplying pi (3.14) times the diameter of the circumference, that is:
circumference = pi*diameter = 3.14*240
circumference = 753.6 cm
that is the solution

Tuesday, they earned $30.00

Using the ratio and the proportional

Josie : Sean : Total

5.5 : 6.5 : 12

x : y : 30

So, x = 5.5 * 30/12 = 13.75

And y = 6.5 *30/12 = 16.25

So, Josie will earn $13.75 and her brother Sean will earn $16.25
