The answer is: [B]: may.
______________________________________________
Plane <em>ABC</em> <span>and Plane </span><em>BCE </em> <u>MAY</u> be the same plane.
_____________________________________________
Note: We can still determine the answer WITHOUT an illustration.
______________________________________________
Explanation:
__________________________________Note that: Two (2) points) determine a line; whereas three (3) points determine a plane.
→ As such, Plane <em>ABC </em>and Plane <em>BCE</em> <u>MAY</u> be the same plane. This would be the case if "<u>Point E</u>" is on Plane <em>ABC</em>. {That is to say, if "<u>Point A</u>" is on Plane <em>BCE </em>}.
→This would be the only "circumstance".
___________________________________________
<span>→ Hence the answer is: [B]: may.</span>
______________________________
Answer choice: [A]: "must" ; is incorrect.
It is clearly INCORRECT to say that:
"Plane <em>ABC</em> and Plane <em>BCE</em> "<u>must</u>" be the same plane._____________________________
Answer choice: [C]: "cannot" is clearly incorrect.
As per the example explained above, it is clearly INCORRECT to say that:
""Plane <em>ABC </em>and Plane <em>BCE</em> "<u>cannot</u>" be the same plane.

Answer:
37.5%
Step-by-step explanation:
15 (total number of correct answers)
divided by
40 (total questions)
= 0.375
you now want to mltiply by 100
0.375 x 100
37.5
therefore Bernie has a percentage of 37.5% or when rounded, he has a 38%.
30 degrees.
Because a right triangle has a 90 degree angle; and a total of 180 degrees.
Therefore:
180-90-2x-x=0
Solve for X:
90-3x=0
3X=90
X=30.
Answer: 1680 inches cubed
Step-by-step explanation:
Volume = Length x Width x Height
V = 20 x 7 x 12
V = 140 x 12
V = 1680 inches cubed
