rational
Yes - if I had an irrational number x, and I added that to the number (7-x), I would end up with 7.If the number is irrational, it can be subtracted from a rational/integer to make another irrational.
The square root of any positive integer can only be a WHOLE NUMBER or IRRATIONAL, so the square root of 7 is irrational.On the other hand, the sum of a rational and an irrational number is always irrational.
No because 7 is a rational number
The square root of 49 is 7, so it is rational.
No. The square root of 49 is plus or minus 7, both of which are integers. And integers are rational numbers - whether they are positive or negative.
-7 is a rational number because it can be expressed as a fraction in the form of -7/1
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
7 is rational.

rational integer whole number
No, it is rational.
You wont be able to add a rational number and an irrational number and get a number not in a fraction ( 3 + 22/7) (21/7 + 22/7 = 43/7) So, yes as you see in the example above it made another irrational number.
