Answer: b. counterexample
A counterexample contradicts the statement or definition you're trying to set up.
For example, if you said that 2x+3x = 7x was true for all x values, then all you need to do is try something like x = 2 to find the original equation simplifies to 10 = 14, which is false. In this case, the counterexample is x = 2 invalidating the equation 2x+3x = 7x.
Answer:
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters ().
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:
Where is the volume of one layer.
Substituting, you get:
1) You are correct.
2) You are correct.
3)
: 3 × 3 × 3 × 3 × 3 × 3 × 3 = 2187
4)
: 10 × 10 × 10 × 10 × 10 × 10 = 100000
5) 20 =
× 5
6) 50 = 2 ×
