Solve for x:
-2 (x -4) - 1/2 (3-4x) = -12

Step-by-step explanation:

-2 (x -4) - 1/2 (3-4x) = -12

                ×(-2)           ×(-2)

4(x - 4) + (3 - 4x) = 24

4x - 16 + 3 - 4x = 24

     -13 = 24            <-- it's not true so it's no solution

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

: )

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
