This is the Pythagorean theorem where the 2 legs of a triangle squared add up to equal the squared hypotenuse (a^2 + b^2 = c^2)

The equation would be
12^2 + 5^2 = x^2

144 + 25 = 169

Ciana wants to buy a shirt that regularly cost 30$.It is on sale for 40$ off. How much is Ciana saving on the shirt?Please help
DerKrebs [107]

Answer:

I think you meant 40% off. If so...

Step-by-step explanation:

First, you have to turn 40 into a decimal - .40.

Then you multiply 30*.40 and get 12.

Subtract 12 from 30 since you are saving 12 dollars.

This means you spend $18 and saved $12.

So, your final answer would be $12.

Hope this helps :)
