What expression is equivenlent to 2/5 divided by 4

4/10 divided by 4

Step-by-step explanation: multiply 2/5 by 2. Multiply on both the denominator and the numerator. If you were to simplify 4/10 you get 2/5 so that way you know if your answer is correct.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
