D. He dilated the dimensions by different factors!
5x + 4y = 2
-5x - 2y = 4
So if we add both the equations 5x will be eliminated.
5x + 4y - 5x - 2y = 4 + 2
4y - 2y = 6
2y = 6
y = 3
As y is 3
x will be
5x + 4 x 3 = 2
5x + 12 = 2
5x = -10
x = -2

Answer:
x = 9
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(24+3) * 3 = x^2
27*3 = x^2
81 = x^2
Take the square root of each side
sqrt(81) = sqrt(x^2)
9 =x
