Decide what number must be added to the binomial to make a perfect square trinomial.

Consider the binomial Ax² + Bx

Step 1: factor out A  ⇒ A(x² + x)

Step 2: divide the "x" term by 2   ⇒   A(x² + x)

Step 3: square the coefficient of the "x" term and add it to the binomial  ⇒   A(x² + x + ()²)

()²

h/o/e/s mad

step-by-step explanation:

si si si

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
