The actual height of the building is 67 1/2 feet
<h3>Complete question</h3>
The courthouse is the tallest building in the city. If it is 7 1/2 inches tall in the model, how tall is the actual building?
Scale factor: 1 inch = 9 feet
<h3>How to determine the actual height?</h3>
The given parameters are:
- Scale height = 7 1/2 inches
- Scale factor: 1 inch = 9 feet
This means that:
7 1/2 inches : Actual = 1 inch = 9 feet
So, we have:
Actual =7 1/2 * 9 feet
Evaluate the product
Actual = 67 1/2 feet
Hence, the actual height of the building is 67 1/2 feet

B)
it is 15 more than A so the A has to go first
2(5x+7) + 2(8x-9)
= 10x + 14 + 16x - 18
= 26x - 4
