Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
The area of the deck is :
A ( deck ) = 8 * 27.63 = 221.04 ft²
The area of the sheet of wood:
A ( sheet ) = 4 * 8 = 32 ft²
221.04 : 32 = 6.9 ≈ 7 ( we need a whole number )
Answer: He should buy 7 sheets of wood to cover the surface of the deck.
