Response:
D. The sidelines are parallel because they are perpendicular to a common line.
Justification:
According to the perpendicular transversal theorem, when a line is perpendicular to one of two parallel lines, it is also perpendicular to the other line. Furthermore, the converse of the theorem states that if two lines are perpendicular to the same line, they must be parallel. Therefore, the sidelines are indeed parallel and also perpendicular to this single line.

Hello!
To find the total length when it is 18 feet 3 inches, we must add both lengths:
18ft 3in + 18ft 3in = 36ft 6in
For the width, add: 10ft 8in + 10ft 8in = 20ft 16in, which converts to 21ft 4in
Therefore, l + w = 57ft 10in

Response:
x = -y-12/5 + 4k
Detailed explanation:
Solve for x in the equation 12 - 5x - 4kx = y
12 - 5x - 4kx = y
Subtract 12 from both sides
-5x - 4kx = y - 12
Factor out -5x - 4kx to get -x(5 + 4k)
-x(5 + 4k) = y - 12
Now isolate x
-x = (y - 12)/(5 + 4k)
Thus, x = -y - 12/5 + 4k
To resolve this kind of question, we need to analyze it on a yearly basis.
At the end of the first year, the tree would experience a growth of 2% = 102% of its initial height.
Year 1: 102% x 50 = 51 feet
Year 2: 103% x 51 = 52.02 feet
