Given f(x) =2x+3 what is the value of f(-5)

If f(x) = 2x + 3, f(-5) = -7

Step-by-step explanation:

You replace the x in the equation with 5 and then distribute and add.

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
