I need help doing this I don't pay attention in class now I'm lost

6498

Step-by-step explanation:

Pay attention in class :)

Okay, so basically, you just need to replace x and y with the corresponding numbers.

So our equation would be:

9 * 2(5 * 7 - 8 * 2) squared

Now we solve with PEMDAS:

9 * 2(35 - 16)squared

9 * 2(19)squared

9 * 2(361)

18 * 361

6498

Let me know if I did something wrong!

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
