To find the missing length, we need to add up the lengths of the two sides that are already given and subtract that sum from the total perimeter.
The two given lengths are 8x - 5 and 9x + 1. Adding them together, we get:
(8x - 5) + (9x + 1) = 17x - 4
Now, we can subtract the sum of the given lengths from the total perimeter:
(24x - 7) - (17x - 4) = 24x - 7 - 17x + 4 = 7x - 3
Therefore, the missing length is 7x - 3. The correct answer is d. 7x - 3.
A triangular park is shown below. If the perimeter of the park is 24x - 7, what is the missing length?
8x - 5
9x + 1
a. 7x - 11
b. 17x - 4
c. 17x + 6
d. 7x - 3
