Answer:
This quadratic equation has 2 solutions.
Step-by-step explanation:
I assume the '?' in your question is meant to be power 2 (²), or else it would not be a quadratic equation. You could write it using the superscript version of 2.
We can solve this equation by expressing it in the form: ax² + bx + c
x² + 9x= -8
x² + 9x + 8 = 0
Now if you know the discriminant, you can simply plug in your values of a, b, and c to see how many solutions there are.
In this case, you would not need the discriminant as there are whole-number factors and hence this can simply be factorised.
x² + 9x + 8 = 0
(x + 8)(x + 1) = 0
For this equation to be true (= 0), x can equal -8 OR -1.
Hence, this quadratic equation has 2 solutions.
Answer:
x = 22
Step-by-step explanation:
Multiply the probability by the cost of the accident:
14,886.05 x 0.071 = 1056.91
Now add the overhead cost:
1056.91 + 110 = 1166.91
The closest answer to this is number D.
Answer:
a
Step-by-step explanation:
it sows that for every 1.35n the N represents the amount ordered
Revenue of Movie A on first weekend = $ 142.44 million
According to the given statement, revenue of movie A was $4.14 million more than the revenue of movie B in their first weekends.
So, we can write:
Revenue of movie A = Revenue of movie B + $4.14 million
Revenue of movie B = 142.44 million - 4.14 million = $ 138.30 million.
Thus movie B take in $138.30 million on its opening weekend.
