Analysis of a cube</h3>
Let be a cube whose <em>side</em> length is and lines and intersects the cube, then we have a <em>cross</em> section formed by points A, C, E, H. Since , , and , then by 45-90-45 right triangle.
In addition, we know that , and . Hence, we conclude that the cross-section is a rectangle. Hence, the area of the <em>cross-section</em> area is:
(2)
If we know that , then the area of the cross-section is:
The shape of the cross-section is a rectangle and the area of the cross section is square units.

Answer:
e. the triangles are congruent
Step-by-step explanation:
Similar means they're alike but are not the same, congruent means they're the same. The triangles are the same so therefore they're congruent.
Also it's congruent because u see the triangles on the bottom and top line? It means that the lines are parallel. So the lines at the side have to be the same length and tilt in an equal way so the top and bottom lines can be parallel
Answer: y = -3
<u>Step-by-step explanation:</u>
-8x - 5y = -1
<u>+8x </u> <u>+8x </u>
-5y = 8x - 1
<u> ÷-5 </u> <u> ÷-5</u> <u>÷-5</u>
y =
y(2) =
=
=
= -3
