OD. 7.2 + (2 +0.4)

Answer 1

`\qquad \qquad\huge \underline{\boxed{\sf Answer}}`

Here's the solution ~

`\qquad \sf  \dashrightarrow \: 7.2 + (2x + 0.4)`

`\qquad \sf  \dashrightarrow \: 7.2 + 2x + 0.4`

`\qquad \sf  \dashrightarrow \: 7.2 +0.4 + 2x`

`\qquad \sf  \dashrightarrow \: (7.2 +0.4) + 2x`

Therefore, the correct choice is A

Answer 2

A. (7.2 +0.4) + 2x

Explanation:

7.2 +1 (2x + 0.4)

7.2 + 2x + 0.4

7.6 + 2x or 2x + 7.6

A. (7.2 +0.4) + 2x

7.6 + 2x or 2x + 7.6

This one is correct

B. (7.2 +0.4) + 2

7.6 + 2

9.6

This one is INcorrect

C. (7 + 2) + 2x

9 + 2x or 2x + 9

This one is INcorrect

D. 7.2 + (2 +0.4)

7.2 + 2.4

9.6

This one is INcorrect

Hope this helps!
