If you would like to know the value of b^2 - 4 * a * c, you can calculate this using the following steps:
x * (x + 8) = 9
x^2 + 8x - 9 = 0
ax^2 + bx + c = 0
a = 1
b = 8
c = - 9
D = <span>b^2 - 4 * a * c = 8^2 - 4 * 1 * (-9) = 64 + 4 * 9 = 64 + 36 = 100
The correct result would be 100.</span>
If you take 1,581 divided by 8, you’ll get 197.625. Round, and you’ll receive about 198. If nick uses 8 dowels for one bird house, he’ll be able to make ABOUT 198 birdhouses.

Answer:
it's 14h
Step-by-step explanation:
The h stands for hours and he needs to work 14 more hours.
The equation A(n)= $175 –(n x $2.75) would define the
amount of money on the<span>
<span>rental
card after (n) rentals. </span></span>
<span>According to the pattern given, $2.75 will be
deducted to the rental card every after Caitlin rents a movie. We can simply
divide the amount of the card which is $175 by $2.75 which we presume the
rental fee. From that, we can have a result of 63.63 rentals using her card. Therefore,
there will be 63.63 weeks Caitlin can afford to rent a movie.</span>
