Answer:

two solutions

Step-by-step explanation:

If you have a discriminant value greater than zero (not zero and not negative), you're gonna have two solutions. For zero discriminant, one solution. For negative discriminant, no solutions at all.

Make sure you remember this. It will save you from solving a quadratic equation which has no solutions.

Round 202.366 to the nearest hundredth
GuDViN [60]
Hello there,

202.366 to the nearest hundredth would be 202.37.

So what I did was I look at the 366 in the problem.

We want to round the to the nearest hundredth.

So what we would do it notice how the 66 in over 50.

The rule is if it's over 50, we round it to the nearest.

So your answer would be 202.37.

Hope this helps.
