Instead of enjoying it as a holiday, one must vote if the truly wants to contribute to the nation building process and bring about a change. A survey was done in a small area in which √9+ 2 - √2 votes were men and 5 √9+2 votes were women.votes were women. Read the above statement and answer the following i. If number of men is equal to number of women The value of x is (a)6 (b)5 (c)8 (d)9 ii. Which mathematical concept is used here (a)Number system (b)Circle (c)Area (d)Statistics iii. The Rationalizing factor of √9+ 2 is (a) √9+ 2 (b) √9− 2 (c) 1 √9+2 (d) 1 √9−2 iv. 9 + 2x is rational and √2 is irrational then 9 + 2x + √2 is (a) an irrational (b) rational (c) an integer (d) None of these v. The product of √9 + 2 - √2 and √9 +2 - √2 is (a)9 (b)-9 (c)2x (d)-2x​

Answer 1

Answer 2

Step-by-step explanation:

(i) x is not specified

(ii) The mathematical concept used here is statistics. (we are given the data of an area)

(iii)  The Rationalizing factor of √9+ 2 is √9- 2

(iv) If 9 + 2x is rational and √2 is irrational then 9 + 2x + √2 is irrational

(v) The product of √9 + 2 - √2 and √9 +2 - √2 is:

 (√9 +2 - √2)*(√9 +2 - √2)

$(√9 +2 - √2)^{2}$

$(3 + 2 -√2)^{2}$

$(5 - √2)^{2}$

(25 + 2 - 2*5*√2)

(27 - 10√2)
