Select the expression that is equal to (9x + 3)– (5x-7). Α 4x + 10
B 14x-4
C14x + 10
D 4x-4

B

Step-by-step explanation:

I think it's B because it's looks equal

A

Step-by-step explanation:

9x-5x=4x

3-(-7)=10

4x+10

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
