What is the sum? 3/x^2 - 9 + 5/x+3 A.) 8/x^2 + x - 6 B.) 5x - 12 / x-3 C.) -5x/ (x + 3)(x-3) D.) 5x-12/ (x+3)(x-3)

Step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
