Answer:
Step-by-step explanation:
The best way to solve something like this is to actually put it on a graphing program like Desmos. I have included that for you on both graphs. You should always graph whatever quadratic you are given even if it gives bizarre answers or no answer at all. At least the graph will tell you if you are close. For example
The middle graph is y = 3x^2 + 8x - 20 This gives you a fractional solution which you will soon learn how to do. The graph will tell you if you are doing it correctly. The graph is deep purple. It is on the graph on the right.
Now try y = x^2 + 4x + 14 which does not give any solution at all. The graph is black. It is on the graph on the rights.
Answer:
28 miles
Step-by-step explanation:
To find how many miles per gallon the car has you would just divide the miles by how how many gallons there are.
for your example it would be 336/12 = 28
Supposing that 20 out of 100 people choose black or gray, the percentage is of 20%.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
Hence, if 20 out of 100 people choose black or gray, the percentage is given by:

Alright! So, we know that in his drawing the living room is 2 millimeters long, and in reality it is 10 meters long. So, to find out how much 1 millimeter is we divide 10 by 2.
[10 ÷ 2] = 5.
One millimeter is 5 meters in reality.
The ratio is 1:5
Answer:
That property would be associative
Step-by-.step explanation:
Because no matter how you change the parentheses in that problem, it would be the same.
