HELP ASAP 1. Which expression has a value of 60 when h = 3?

a 2( 5h)

b h3

c 20h

2. Convert the following word phrase to an algebraic expression:

The product of a number and 12.

a 12n

b 12 ÷ n

c 12 + n

d 12 - n

1= C. 20h

2= A. 12n

Step-by-step explanation:

1= 20(3)=20x3=60

2= you put your digits before variables. in this case your digit is 12 and you variable is n. so it would be 12n. also because the product is multiplication and a variable (which represents an unkown number) directly next/behind a digit (in this case 12) means to multiply.  

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
