Step-by-step explanation:
Area 1 = the rectangle
8×3=24cm²
Area 2= semi circle
3.14r² 314/100×4×4 = 50.24cm²
add. 24+50.24 = 74.24cm² ( 10th)
<h2>= 74.2</h2>
We want to make x^2-3x into a perfect square trinomial. An example of such a trinomial is x^2 + 6x + 9, which is equivalent to the square of (x+3).
From x^2-3x we see that the coefficient of x is -3. Divide this coefficient, -3, by 2, obtaining -3/2. Now square this result: square -3/2. Result: 9/4.
Adding 9/4 to x^2-3x makes x^2-3x into a perfect square trinomial.

Answer:
The total yearly cost is $300 at each gym for 50 visits.
Step-by-step explanation:
Healthy Gym: 6n = t
Fitness Gym: 50 + 5n = t
When n = 50 visits, then...
Healthy Gym: 6(50) = $300
Fitness Gym: 50 + 5(50) = $300
