Simplify into 5 times 9/5.
Multiply to get 45/5.
Simplify again into 9.
You would do 21 divided by 3 and get 7.
The answer is 7 kids are in the line.
Please vote my answer the brainiest if it was helpful!!
8/7 as an improper and 1 and 1/7 for proper.
Answer:
Step-by-step explanation:
The Fundamental Theorem of Algebra states that the number of complex roots a polyomial has is equal to its highest exponent. This is a squared polynomial; second degree; quadratic. When it is factored, no matter what types of numbers you get as the solution, you will ALWAYS have 2 of them. When this quadratic is factored, we get that x = 3 and x = 3. That means that this is a quadratic that touches the x-axis at (3, 0). It doesn't go through, it only touches. We do have 2 roots, but since they're the same, we say we have a multiplicity 2 of that root. The closest you'll come to that in your choices is A. Apparently your text refers to multiplicity 2 as a double root.
hope this helps :)
your question helped me and so ill help you
