Answer:
The answer is 21 if you use PEMDAS.
Answer:
The roots of the equation are x=-3 and x=-2.5
Step-by-step explanation:
<u><em>The correct quadratic equation is</em></u>
2x^2+11x+15=0
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The roots of the equation are x=-3 and x=-2.5
Hmm. I think true in this case
Well, if 10 people are heading to the park and each car holds 5 people, we can write the equation, "5x = 10" so, we need to get x by itself. To do that we need to get rid of the five. Whatever we do to one side, we do to the other. So 5/10 = 2 so, 2 cars are needed. Hope that helps! :)
