Plz i need . idk the answer , i will mark brainiest! combine like terms. like terms 1/2x + 1/8x a. 1/8x b. 3/8x c. -1/8x d. -1/16x

5/8x

Step-by-step explanation:

When combining like terms in this expression, you are essentially adding 1/2 and 1/8. To do this make sure both fractions have common denominators.

1/2 * (4/4) = 4/8

Now you can add them together.

4/8 + 1/8 = 5/8

5/8x is your answer.

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
