Answer:

Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.

timurjin [86]

Answer:

21

Step-by-step explanation:

You can do it two different ways.

1st. Find the scale factor by dividing - 75/25=3 or 72/24=3

This means the scale factor is three

Then multiply the remaining side (7) by the scale factor (3) to get: 21

2nd. Use the Pythagorean Theorem - 75²-72²=x²

441 = x²

√441=x

x=21
