Answer:

0.02 (rational)

2 (rational)

Square root of 2 (irrational)

Square root 1/2 (irrational)

Step-by-step explanation:

Rational numbers are numbers that can be in form of a/b such that a and b are not zeros. In other words, a and b are integers ranging from 1 to infinity.

Conversely, irrational numbers are numbers that are endless and are non repeating digits after decimal point.

Thus, from the questions above;

0.02 =   \frac{2}{100}  = rational \: number

2 =  \frac{2}{1}  = rational \: number

\sqrt{2}  = 1.41421356 = irrational \: number

\sqrt{ \frac{1}{2} }  = 0.70710678 = irrational \: number

I don't know how to solve this and the answer isn't 4 or 0 so what is it?4=-4+a​
nevsk [136]
The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.
