Answer: 36 cm^2
Step-by-step explanation:
Hello!
We can start by finding the cube root of 216, which is 6. This is the length of each side of the cube.
Now, the area of the base of the cube is equal to 6^2=36 cm^2.
-1/2w-3/5=1/5w
-5w-6=2w
-5w-2w=6
-7w=6
w = -6/7
Answer: x=12
Step-by-step explanation:
1. Accoding to the Side-Splitter Theorem, if a line interesect two sides of the triangle and it is parallel to the third side, then the other two sides are divided by the line proportionally.
2. Then, you can form the following proportion:

3. Substitute values and solve for x:

Answer:
