Answer: 9

Step-by-step explanation:

The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.

Music lessons cost 45 dollars per hour. Evaluate 6 hours
faltersainse [42]

Answer:

If each of your music lessons cost you 45 dollers each hour. If you do 6 hours than your price will be 7.5$ because we did 45 divided by 6

You divide the number of hours which is 6 with the cost per hour which is 45, and you are left of with 7.5$ or what I like to think of it as, 7.50$

Hope this helps

Hey there!

<h2>ANSWER: 10^7</h2><h2>EXPLANATION:</h2>

10*10*10*10*10*10*10 \text{ as a power}

10(1)*10(2)*10(3)*10(4)*10(5)*10(6)*10(7)\\\text {It was multiplied 7 times}

Since it was multiplied 7 times, you would write it like this.
