<h2>Solving Quadratic Equations with the Quadratic Formula</h2>
<h3>Answer:</h3>
and 
<h3>Step-by-step Explanation: </h3>
Recall:
if we have a quadratic equation,
, where
,
and
are real numbers and
,
.
Given:

Solving for
:

Solving with the positive value:

Solving with the negative value:

Lower quartile (xL): 68
Upper quartile (xU): 88
Interquartile range (xU-xL): 20
The measure of x is 24 degrees
One straight line is 180 degrees
We already have another line that forms an angle with the straight line and it gives u 156
So just subtract 156 from 180 to see what remains and that’s the answer
He would spend $27.50, because each bag costs $5.50. Multiply that by 5 and you have your answer :)
You'll want to first simplify the expression

.
To do that, first distribute the
