Determine the number of solutions using the discriminant D=b^2-4ac
D=m^2-4•3•(-3)
Calculate the product D=m^2+36
Since D > 0 for any value of m
The quadratic equation has 2 real roots.

Answer:
-2.45
Step-by-step explanation:
You are asked to EVALUATE 8.722÷(−3.56). Here you are dividing a positive number by a negative one, and so you expect that the result (quotient) will be negative.
Thus, 8.722÷(−3.56) becomes -8.722÷(3.56) = -2.45
Answer:

Answer:
Question
An expression can often be used to model a real-life situation. For each of the following expressions, write a real-life situation using money as the context. Then, evaluate the expression and interpret the result in terms of the situation. Here's an example.
The following situation is modeled by the expression -24.50 + 100.00: Jonathan overdrew his checking account by $24.50. He then transferred $100.00 from his savings account to his checking account. His new checking account total is $75.50.
Make sure to use complete sentences in your answers.
1) $8.15 + $11.99
2) $20 - $18.04
3) 7($1.45)
4) 42.08 / 4
It's too short. Write at least 20 characters to explain it well.
