At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?

D) x - 0.2x

Step-by-step explanation:

The hat has a regular price of x dollars.

This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x

The discounted price will be the price of the hat less the discount which means the formula will be;

= Price - discount

= x - 0.2x

step-by-step explanation:

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
