- 7 and -5 are integers, so they are rational.
- is already a fraction with integers. It is rational.
- 5.79 is a terminating decimal. It is rational.
- The number π is a famous irrational number. It does not terminate nor repeat.
- is not a perfect square. It is irrational.
- is a perfect square, but it is simplified to a complex number. <em>Complex numbers are not rational. </em>

Hope this helps you. I apologize if it’s incorrect.
0.8 and 0.80 are named the same because both of them numbers have an 8 in the tenths place and a zero in the hundredths place. No matter how many zeros you add on to the end of the decimal, it does not change its value.
Answer:
the requirements are missing:
- express the height of the rectangle in terms of w
- express the area of the rectangle in terms of w
1) the height of the rectangle is:
w + h + h + w = 500 + w
2w + 2h = 500 + w
2h = 500 + w - 2w = 500 - w
h = (500 - w) / 2 = 250 - 0.5w
2) the are of the rectangle is:
w x h = w x (250 - 0.5w) = 250w - 0.5w²
