First blank: Definition of a right triangle.
A right triangle is a triangle that has exactly one right angle.
Second blank: sin M = h/p, and sin P = h/m
The ratio for sin. is opposite over hypotenuse.
Third blank: Substitution property of equality
In this step, we are substituting the value of h into the first equation.
Fourth blank: Division property of equality
We are dividing both sides of the equation by the same divisor.
Hope this helps!

Answer:</h3>
A. 3x² +6
<h3>
Explanation:</h3>
(f-g)(x) = f(x) -g(x) = (4x²+1) -(x²-5) . . . . . substitute the function definitions
... = 4x² +1 -x² +5 . . . . . . . . . . . eliminate parentheses
... = (4-1)x² +(1+5) . . . . . . . . . . . collect like terms
... = 3x² +6
