Answer:
F: 48
Step-by-step explanation:
Let x be the length of the side of the cube. RQ can be expressed as a triangle consisting of a diagonal of a face of the cube and the side length x. By the pythagorean theorem, we know that a^2+b^2=c^2. So, we can express the diagonal as x^2+x^2=c^2, giving us the value of c to be 
. Now, we can once again use the pythagorean theorem to find RQ^2=2x^2+x^2=3x^2, so RQ=
=12, so x=
. To find the area of the shaded part, we multiply the length times width which gives us 
. So, the area of the shaded face of the cube is F: 48.

Answer:
Yes
Step-by-step explanation:
If we multiply them out, we get 6x + 2.4 for the first one and 6x + 2.4 for the second one, therefore they are the same.
Sami arrives at the library at 4:15. Why? Well is says she took 15 minutes to walk to karlas house so when she arrives it’s 4:00 PM. Than, she stays at karlas house for 5 minutes which puts her at 4:05 PM. After that is Sami took 10 minutes to get to the library so that puts Sami at 4:15 PM. Hope this helps!
True. The only area where a line parallel to one side would be able to intersect both other sides would be in a place that proportionally divides the other sides.
