                              4/(x+1) = 3/x + 1/15
Should we make common denominators with everything, we get
           4*15*x / [15x(x+1)] = 3*15*(x+1)/[15x(x+1)] + x(x+1)/[15x(x+1)]
Multiply both sides of the equation by the denominator to cancel them
                                         60x = 45(x+1) + x(x+1)
                                         60x = 45x + 45 + x^2 + x
                       x^2 - 14x + 45 = 0
                           (x-9)(x-5) = 0
The answer to this question is that the solutions are x=9 and x=5.

Find c.

Alexxx [7]

9514 1404 393

Answer:

14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

c/sin(C) = b/sin(B)

c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

c ≈ 14.9 cm
