Explain how you can tell when a formula represents a length an area or a volume

AlekseyPX

Do you mean how you can tell between an area formula and a volume formula? Well usually like on a reference sheet it says the shape and the letter a or v, a representing area and v representing volume. I hope this helps, if it doesn't please tell me in the comment section

Step-by-step explanation:

3x - 2y = 12

Substituting y = 9, we find:

$3x - 2 \times 9 = 12 \\ \therefore \: 3x - 18 = 12 \\ \therefore \: 3x = 12 + 18 \\ \therefore \: 3x = 30 \\ \therefore \: x = \frac{30}{3} \\ \therefore \: x = 10 \\ \therefore \: A (...., 9) = A (10, \: 9)$
