Answer:
C. Rectangle and Cube
Step-by-step explanation:
It's actually pretty easy to figure this out because all you have to do is look at the shape, and try to find what to shapes made this figure. When you look at a cuboid (rectangular prism), you can see how the answer choices have one 2D shape, and one 3D shape. Well after looking at the Cuboid, we can see that there are rectangles on the faces, and this would be the 2D shape, and then we have a big cube holding those faces together, and the cube would be our 3D shape.
Hope this helps :)
Answer: CD = 10
Identify the given information.
FG = 15
GE = 21
FE = 36
CD = x
DE = x + 4
Form your equation. Due to the Side-Splitter Theorem, FG/GE = CD/DE.
15/21 = x/x + 4
Cross-multiply and solve.
15(x + 4) = 21x Distributive Property
15x + 60 = 21x Subtract 15x from both sides
60 = 6x Divide by 6 to both sides
x = 10 Answer!
