Question

74. A portion of a board has length x feet. The other part has

Answer 1

Step-by-step explanation:

Given that,

• Length of the one portion of the board = x feet
• Length of the another portion = (7x – 9) feet

According to the question,

$\longrightarrow$ Total length = Sum of the length of the two pieces

$\longrightarrow$ Total length = {x + (7x – 9)} feet

$\longrightarrow$ Total length = {x + 7x – 9} feet

$\longrightarrow$ Total length = (8x – 9) feet

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