Answer:
40 feets
Step-by-step explanation:
Given that :
Area of house = 1200 square foot
Width of house = 30 feets
Since, the house is rectangular :
Area of a rectangle = Length * Width
Hence,
Area of house = width of house * length of house
1200 ft² = length * 30 ft
Length = 1200 ft² / 30 ft
Length = 40 feets
Hence, length of house = 40 feets
+22
Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.
Then -2 times g(4) = -2(-11) = +22
