Let's evaluate the expressions in the image step by step.

29. $4(3 + 5) - 3(6 - 2)$

1. First, solve the expressions inside the parentheses:

   • $3 + 5 = 8$
   • $6 - 2 = 4$

2. Then multiply:

   • $4 \times 8 = 32$
   • $3 \times 4 = 12$

3. Finally, subtract:

   • $32 - 12 = 20$

So, the answer is 20.

32. $4(3 - 1)^3 + 7(6) - 5^2$

1. Solve the expressions inside the parentheses:

   • $3 - 1 = 2$

2. Raise to the power:

   • $2^3 = 8$

3. Then multiply:

   • $4 \times 8 = 32$
   • $7 \times 6 = 42$

4. Find the square of 5:

   • $5^2 = 25$

5. Add and subtract:

   • $32 + 42 - 25 = 49$

So, the answer is 49.

35. $8(7.3 + 3.7 - 8) \div 2$

1. Solve the expression inside the parentheses:

   • $7.3 + 3.7 = 11$
   • $11 - 8 = 3$

2. Multiply:

   • $8 \times 3 = 24$

3. Finally, divide:

   • $24 \div 2 = 12$

So, the answer is 12.

38. $\frac{12^2 - 4(6) + 1}{11^2}$

1. Solve the squares:

   • $12^2 = 144$
   • $11^2 = 121$

2. Multiply:

   • $4 \times 6 = 24$

3. Perform the arithmetic in the numerator:

   • $144 - 24 + 1 = 121$

4. Finally, divide:

   • $\frac{121}{121} = 1$

So, the answer is 1.
