To land on 0 the number would need to end with a .5 or .0 since that is the only way .0 can occur with counting down by.5( half)
She would have to study about 48 hours to get a score of 97.
Hopefully that helped! :)
18 + 81 = 9(x²<span> + 6x + 9)

When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²

Answer:
12/x^5
Step-by-step explanation:
The fractions are multiplied in the usual way. The applicable rule of exponents is ...
(x^a)(x^b) = x^(a+b)
