Answer:
(-5,3)
Step-by-step explanation:
<em><u>Method</u></em>
There are several ways you can do this, but one of the best ways is to use a graphing coordinate calendar. The most popular one is Desmos Graphing Calculator. I've attached an image of my work below using the system.
<u><em>Answer</em></u>
As you can see, both equations intersect at a certain coordinate point. This coordinate point is the point you need for the answer. The intersection is (-5,3).

Answer:
C
Step-by-step explanation:
x² + 6x = 18
To complete the square, take the coefficient of the x term, halve it, square the result, then add to both sides.
(6/2)² = 3² = 9
x² + 6x + 9 = 18 + 9
(x + 3)² = 27
x + 3 = ±√27
x = -3 ± √27
Multiply the dimensions by 1.5 and Pamela's suitcase becomes 42" x 24" x 12".
<span>Volume of 28" x 16" x 8": 3584 in^3 </span>
<span>Volume of 42" x 24" x 12": 12,096 in^3 </span>
<span>The volume ratio is 3.375, and yes, you have to cube it.</span>
