Question

The total length of the fence around a quadrilateral-

shaped garden shown is 3a2 + 15a + 9. What expression
represents the missing fence length?
22-7
50
10a-2

Answer 1

The missing fence length can be determined by subtracting the total length of the given sides from the total length of the fence around the quadrilateral-shaped garden.

Step-by-step explanation:

The missing fence length can be determined by subtracting the total length of the given sides from the total length of the fence around the quadrilateral-shaped garden.

Expression: (3a^2 + 15a + 9) - (A + B + C)

Example: If the total length of the given sides A, B, and C is 4a^2 + 8a + 6, then the expression for the missing fence length will be (3a^2 + 15a + 9) - (4a^2 + 8a + 6).
