Answer :
Let's assume the opposite of the statement i.e., 3 + √5 is a rational number.


Since, a, b and 3 are integers. So,

Here, it contradicts that √5 is an irrational number.
because of the wrong assumption that 3 + √5 is a rational number.

Hence, 3 + √5 is an irrational number.
the answer is 2/3 and the y intercept is 2. we can find the y intercept because its where the line crosses the y axis and the slope by calculating rise and run using 2 points bebe :)
51, 53, 55, 57, 59. it's simple.
C=2•pi• R
D=6 then the radius is 3
2•Pi•3 =18.85
Likely because she has 1 out of 6 chances of rolling a 4
