What is a ratio that describes 4:3

For example, older televisions have a 4∶3 aspect ratio, which means that the width is 4/3 of the height (this can also be expressed as 1.33∶1 or just 1.33 rounded to two decimal places).

Step-by-step explanation:

f(g(x)) = 9x^2 - 3x - 4

Step-by-step explanation:

Assuming it’s

f(x) = x^2 + 3x - 2

and g(x) is linear:

f(g(x)) = (3x - 2)^2 + 3(3x - 2) - 2

= 9x^2 -12x + 4 + 9x - 6 - 2

= 9x^2 - 3x - 4
