The sunken ship and the airplane are the same distance from sea level.
This is because -4 and 4 are on exact opposite sides of the number line.
Answer: Length is 30 feet and width is 7 feet.
Step-by-step explanation: The dimensions of the rectangle are not given, but the clues given in the question are such that, if the width is W, then the length would be two feet more than four times the width. In other words, the length would be, two plus four times the width, which can be expressed as
2 + 4W. The perimeter given as 74 feet is calculated as
Perimeter = 2(L + W)
If perimeter equals 74, length equals 2 + 4W and width equals W, then the perimeter can be expressed as
74 = 2(2 + 4W + W)
74 = 2(2 + 5W)
74 = 4 + 10W
Subtract 4 from both sides of the equation
70 = 10W
Divide both sides of the equation by 10
W = 7
Hence, if the width is 7, the length would be calculated as
Length = 2 + 4W
Length = 2 + 4(7)
Length = 2 + 28
Length = 30.
Therefore the length equals 30 feet and the width equals 7 feet.
