This question has this set of answer choices:
a) when the plane cuts three faces of the cube, separating one corner from the others
b) when the plane passes through a pair of vertices that do not share a common face
c) when the plane is perpendicular to the base and intersects two adjacent vertical faces
d) when the plane makes an acute angle to the base and intersects three vertical faces
e) not enough information to answer the question
The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others
You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.
Hope this helps. <3 (sorry if it’s a little blurry)
Answer:
(r-7)(r+2)
Step-by-step explanation:
First, let's look at the -14. Possible factors for that number are (-2, 7) (2, -7) (1, -14) and (-1, 14).
Now, let's look at the -5. How can we make -5 with the pairs that we just found?
The only possible way is 2 and -7 (added together equals -5)
Answer:

Step-by-step explanation:
Total amount of water = 500 ml
Mary drank = 400 ml
<u>Left:</u>
= 500 ml - 400 ml
= 100 ml
This was divided equally among 4 friends.
So,
<u>Each friend got:</u>
= 100 ml/4
= 25 ml
