5) The solution of (2x - 1)2 = 9 is equal to d) 21
a) - 1
b) 2
c) - 1,2
d) None of these
6) The GCD of x2 - 2xy + y2

Q5 d

Step-by-step explanation:

(2x-1)2=9

4x-2=9

4x=9+2

4x=11

x=2.75

ans: none of these

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
