Factor ab + bc+ b² + ac. A. (a + b)(b + c)

B. (a + c)(b + c)

C. b(a + b)(b + c)​

A. (a + b)(b + c)

Step-by-step explanation:

b( a + b ) + bc + ac

b( a + b ) + c ( b + a )

= (a + b)(b + c)

hope it helps!

A

Step-by-step explanation:

a(b+c)+bc+bb

a(b+c)+b(c+b)

(b+c)(a+b)

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
