The sum or product of a non-zero rational number and an irrational number is always

1.rational.
2.irrational.
3.a repeating decimal.
4.a fraction.

Option 2 - Irrational              

Step-by-step explanation:

To find :  The sum or product of a non-zero rational number and an irrational number is always  

Solution :

By the statement,

→ "The sum of a rational number and an irrational number is irrational."

Example : Let a rational number 3 and irrational number

Sum of rational and irrational number

5.236067977.... is a irrational number as if you add a non-repeating and non-terminating decimal to a repeating decimal, you will have a repeating decimal.

→ "The product of a non-zero rational number and an irrational number is irrational."

Example : Let a rational number 3 and irrational number

Sum of rational and irrational number

6.708203931...... is a irrational number as If you multiply any irrational number by the rational number it gives you irrational except zero which is rational.

Therefore, Option 2 is correct.

The sum or product of a non-zero rational number and an irrational number is always  irrational.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
