What is the value of 2x2 – 2(x+4) when x=5? a) -32 b) 24 c) 32 d) need hellpp now

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

-14 is the answer

hope this : ))

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

first one because it can't have a fraction in it
