Answer:

Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant
(or, if b is an even number, 1/4 of it) is zero.
<u>I see it! I see it!</u>
Stare at it for a while. First term is
, third term is
, we are missing a double product, but we can play with k. For the LHS to be
you just need
.
<u>I don't see it...</u>
Then number crunching it is. Set the discriminant to 0, solve for k

<h3>$330</h3>
Step-by-step explanation:
Half of 40 is 20 and luckily they already gave us how much she would earn if she worked 20 hours.
So all we have to do is multiply the amount of money she earned when she worked 20 hours by 2 to see how much she earned when she worked 40 hours.
20 hours:165 dollars or 20:165
20 x 2= 40 and 165x2=330
So if Monique worked 40 hours she would earn $330.

Hope this helps you. Please mark as brainliest. It helps a lot. ^_^
Okay so you put the numbers in order:
70, 74, 81, 82, 83, 91, 94.
Then you find the median which will be Q2:
82.
Once you have the total median, you find the midpoint of the first and last part:
70, 74, 81. Midpoint/Q1=74
83, 91, 94. Midpoint/Q3=91
Now that you have that, you subtract Q3 and Q1.
91-74=17
17 is your IQR.
