Question

The expression below shows a sum multiplied by a factor:

3(2+6D)
Which options are equivalent to the expression above?
Select ALL that apply.


A (3 x 2)+(3 x 6d)

B 6+6d

C 3+2+6d

D 2+ (3 x 6d)

E 6+18d
3(2+6d)

Answer 1

A and E

Explanation:

I see no other correct answer option.

3(2 + 6D) = 3×2 + 3×6D = 6 + 18D

= (3×2)+(3×6D)

with or without brackets this is the same thing as per the priorities of mathematical operations (first multiplications and divisions, and only then secondly additions and subtractions).
