Step-by-step explanation:
1/sin^2A -cos^2A/sin^2 A. ~tan = sin/cos
(1-cos^2)/sin^2A. ~ take lcm
sin^2A/sin^ A. ~ 1-cos^2A = sin^2A

Since the 50 remains the same every time, is has no letters next to it in the equation. The 20, however, is multiplied by the amount of hours, and will therefore have an h next to.
20h + 50- the answer is a.

Answer:
y = 
OR y = 
Step-by-step explanation:
Our quadratic equation is: (5y + 6)² = 24.
The first step is to square root both sides:
5y + 6 = ±√24 = ±2√6
Now subtract 6 from both sides:
5y = ±2√6 - 6
Finally divide by 5 from both sides:
y = OR y =
And, those are the solutions to the equation.
