74. A portion of a board has length x feet. The other part has length (7x – 9) feet. Express the total length of the board
as a simplified expression in x.

Step-by-step explanation:

Given that,

According to the question,

Total length = Sum of the length of the two pieces

Total length = {x + (7x – 9)} feet

Total length = {x + 7x – 9} feet

Total length = (8x – 9) feet

Therefore, the total length of the board as a simplified expression in x is (8x – 9) feet.
