  Evaluate:

(13 + 7)2 + (6 + 2) ÷ 5 ÷ 9

For full marks, your answer should be accurate to at least two decimal places.

Question 2 Answer

a.
65.18

b.
64.18

c.
-64.18

d.
64.118

To solve the expression \( (13 + 7) \times 2 + (6 + 2) \div 5 \div 9 \), follow the order of operations (BIDMAS/BODMAS).

1. **Brackets**:  
   - \( 13 + 7 = 20 \)  
   - \( 6 + 2 = 8 \)

2. **Multiplication**:  
   - \( 20 \times 2 = 40 \)

3. **Division**:  
   - \( 8 \div 5 = 1.6 \)
   - \( 1.6 \div 9 \approx 0.18 \) (rounded to two decimal places)

4. **Addition**:  
   - \( 40 + 0.18 = 40.18 \)

Given the choices, it seems the closest correct choice would be \( 40.18 \), but none of the provided options match this result directly. Let's recheck to ensure everything aligns correctly:

If the brackets are applied as written:
\[
(13 + 7) \times 2 + \left(\frac{6 + 2}{5 \times 9}\right)
\]

Still, the key here is \( 40.18 \) is not matching any of the options correctly. I would need clarification on whether there is a misprint or miscalculation in the options provided.

If assuming \( \times 2 \) may be neglected or more clarity needed.

Please double-check the formula or choices provided, and I will recalculate as needed.
