answer:
option a) , c) and d)
step-by-step explanation:
let us see every option one by one
a) (0.5)^2= 0.5 x 0.5 = 0.25
hence it is true
b) -0.2+(-0.05)
-0.20-0.05=-0.25 ≠0.25
hence false
c) |-3+2.75|
=|-3.00+2.75|
=|-0.25| = 0.25 as the mode of any negative number is positive
hence it also true
d) .25) = 0.25 and negative of any negative integer makes it a positive
hence it is also true
e) 2x-1.75x
= 0.25x
here though we have same coefficient but technically it is not a correct answer as we have an x with 0.25. hence it is false
