Answer 2

Let's break down the expression step by step:

1. Convert feet and inches to inches:

   • 4 feet = 4 * 12 inches = 48 inches
   • 8 inches = 8 inches

2. Calculate the expression within parentheses first:

   • 10 + 9 = 19

3. Now, let's substitute these values back into the original expression:

   • (48 + 8) - 10(19) + 2205 + 10' + 210' - (2 + 3)

4. Perform the operations inside parentheses:

   • 56 - 10(19) + 2205 + 10' + 210' - (2 + 3)

5. Multiply 10 by 19:

   • 56 - 190 + 2205 + 10' + 210' - (2 + 3)

6. Perform the addition and subtraction operations:

   • 56 - 190 + 2205 + 10' + 210' - 5

7. Convert the feet to inches:

   • 56 - 190 + 2205 + 120 + 210' - 5

8. Convert 210 feet to inches:

   • 56 - 190 + 2205 + 120 + 2520 - 5

9. Perform the addition and subtraction operations:

   • 3151 - 195

10. Finally, subtract 195 from 3151:

• 3151 - 195 = 2956

So, the result of the expression is 2956 inches.
