Select all of the following expressions that are equivalent to 0.25. (0.5) ^2 (-0.2) + (-0.05) |-3+2.75| - (-0.25) 2x-1.75x

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) - (-0.25) = 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

(0.5) ^2 = 0.25 yes

(-0.2) + (-0.05) = - 0.25 no

|-3+2.75| = |-0.25| = 0.25 yes

- (-0.25) = 0.25 yes

2x-1.75x = 0.25x no
