• A. $7h+9$
• B. $3h-13$
• C. $16h$
• D. $7h+13$

Answer 1

The correct option is A

$7h+9$

Step 1: Given:

The number of seashells collected by you $=(11+2h)$
The number of seashells collected by your friend $=(5h-2)$

The total seashells have you and your friend collected can be obtained by adding the number of sea shells obtained by each of you

= (The number of seashells collected by you) + (The number of seashells collected by your friend)

$$\begin{gathered} =11+2h+5h-2 \\ =2h+5h-2+11\{Commutativeproperty\} \\ =7h+9\{Combineliketerms\} \end{gathered}$$

So, option (F) is correct

Final Answer: $7h+9$

So, option (F) is correct
