12 + 4 · 3 - 15

To solve this, we have to use the order of operations. In the order of operations, multiplying and dividing come first while addition and subtraction come later.

12 + 4 · 3 - 15

= 12 + 12 - 15

The order doesn't matter for subtraction and addition, since you'll end up with the same answer. (In this case, I'll be doing addition first to avoid negative numbers)

12 + 12 - 15

= 24 - 15

= 9

That's your answer! Happy Studying~

Pythagorean Theorem with Known Legs
stepan [7]

you're given the pythagorean theorem, which is a^2 + b^2 = c^2.

what you're trying to find is ?, which is the number under the radical.

let's pretend one leg is a and the other is b.

a = 9

b = 10

so let's plug it into the equation. we get 9^2 + 10^2 = c^2

so that equals 81 + 100 = c^2

181 = c^2

so c will equal the square root of 181. therefore, ? = 181.

hope i helped! good luck.
