H = cost per hour
15 = the rental price
0.75H = the hourly rental
Step-by-step explanation:
H = Cost per Hours
H = 15 + 0.75H
H = 15 + 0.75 * 4
H = 15 + 3
H = 18
Answer:
16.25
Step-by-step explanation:
6.5 + 5 = 32.5/2 = 16.25
To create a perfect square trinomial, halve the x coefficient, square it, and then add that value.
In the case of x² + 6x, we would have 6 to get 3, then square 3 to get 9.
We would add 9 to make a perfect square trinomial.
<u>
</u><u>Why this works</u>
A perfect square trinomial is designed to factor to some value (x+n)².
When you FOIL this you get x² + 2nx + n².
As you can see, if you wanted to find the value of that n², you could take that x coefficient 2n, halve it to get n, and then square it to get n²!
