Answer:heyyy there...the answer is b that is -12x^3+12x^2-20
Step-by-step explanation:
<h3>f(x)=
-12x^3+19x^2-5</h3><h3>g(x)=
7x^2+15</h3><h3>f(x)-g(x)=(
-12x^3+19x^2-5)-( 7x^2+15)...{while opening the bracket the sign of the second polynomial changes accordingly}</h3><h3>
it becomes -12x^3+19x^2-5-7x^2-15</h3><h3>
=-12x^3+12x^2-20</h3><h3>

There are 4 As and 3 Bs, so the ratio of Bs to the total number of As and Bs is ...
... (count of Bs) : (count of As + count of Bs)
... = 3 : (4 + 3)
... = 3 : 7
Expressed as a fraction, this is
... 3/7
