Answer:

1. x = 36

2. x = -2, x = 5

Step-by-step explanation:

Secant - Secant Power Theorem: 12(12 + x) = 10(18)

144 + x = 180

x = 36

Chord - Chord Power Theorem: (x - 2)(x + 7) = 4(2x - 1)

x^2 + 5x - 14 = 8x - 4

x^2 - 3x - 10 = 0

Factor:

(x + 2)(x - 5) = 0

x = -2, x = 5

Simplify 7 square root of 3 end root minus 4 square root of 6 end root plus square root of 48 end root minus square root of 54

Katen [24]

$7\sqrt3-4\sqrt6+\sqrt{48}-\sqrt{54}\\\\=7\sqrt3-4\sqrt6+\sqrt{16\cdot3}-\sqrt{9\cdot6}\\\\=7\sqrt3-4\sqrt6+\sqrt{16}\cdot\sqrt3-\sqrt9\cdot\sqrt6\\\\=7\sqrt3-4\sqrt6+4\sqrt3-3\sqrt6\\\\=\boxed{11\sqrt3-7\sqrt6}$

C. 5x - 2y = 16 is your answer

plug in each point into the equation.

(2, -3)

x = 2, y = -3

5(2) - 2(-3) = 16
10 + 6 = 16
16 = 16 (True)

(4,2)

x = 4, y = 2

5(4) - 2(2) = 16
20 - 4 = 16
