Answer:
-6c + 7
Step-by-step explanation:
To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.
3c + (-9c) = -6c
The 7 stays the same, so the simplified expression is -6c + 7.

Answer: 118 feet
Step-by-step explanation:
For a rectangular shape: Area = W × L
450 = 9 × L
450 ÷ 9
L = 50
Perimeter of a rectangular shape = 2L + 2W
Perimeter = (2 × 50) + (2 × 9)
= 100 + 18 = 118 feet
