I mean I think so I’m not completely sure it’s a really hard question
This is called the Pythagorean theorem : a ² + b ² = c ². You can substitute any of the variable with any of the known numbers and then you all you have to do is isolate the variable. I hope that helps!!

Answer:
1. rational number
2. a positive rational number
Step-by-step explanation:
A rational number is a number that can be expressed as a simple fraction. When two rational numbers are multiplied together, the only logical answer would be for the outcome/product to also be rational.
The reciprocal of a positive rational number is also a positive rational number because if the original number was negative, the reciprocal would also be negative since the signs wouldn't change (in this case, the original number is positive). Since the original number is already a rational number, just by flipping it (the reciprocal), it would not change to an irrational, but instead stay the same.
Answer:
x=-4 x=-2
Step-by-step explanation:
x² + 6x + 8 = 0
x² +2x+4x + 8 = 0
x(x+2)+4(x+2)=0
(x+4)(x+2)
x=-4 x=-2
