Answer: The equation shall be
8 = 4W
Step-by-step explanation: The perimeter has been given as 46 feet, whereas the length and the width are not yet given. But the clue we have states that “the length is 19 feet longer than the width,” which means, if the width is W then the length shall be 19 plus W. We can express the dimensions as;
Length = 19 + W
Width = W
We can now express the perimeter as follows;
Perimeter = 2(L + W)
46 = 2(19 + W + W)
46 = 2(19 + 2W)
46 = 38 + 4W
Subtract 38 from both sides of the equation
8 = 4W
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
using the pythagorean theorem
a^2+b^2 = c^2 where c is the hypotenuse
9^2 +12^2 = x^2
81 + 144 = x^2
225 = x^2
taking the square root of each side
sqrt(225) = x
15 =x
x = 15 inches
