Nadia says the hypotenuse of this right triangle has a length of 73 because the Pythagorean theorem states that (28 + 45) square
Vaselesa [24]

Answer:

Third answer (she is incorrect because she should have squared each leg length and then found the sum.)

Step-by-step explanation:

The pythagorean theorem states that a²+b²=c². This is not equivalent to (a+b)²=c² (due to FOIL expansion, this expands to a²+2ab+b²=c²).

This matches with the third answer, as she has to do a² and b≥ separately.

**This question involves expanding perfect squares, which you may wish to revise. I'm always happy to help!
