Answer:
c
Step-by-step explanation:
Expressing the proportion in fractional form , that is
[tex]\frac{x+4}{x+12}[/tex] = [tex]\frac{x-1}{x+5}[/tex] ( cross- multiply )
(x + 4)(x + 5) = (x + 12)(x - 1) ← expand both sides using FOIL
x² + 9x + 20 = x² + 11x - 12 ← subtract x² + 9x from both sides
20 = 2x - 12 ( add 12 to both sides )
32 = 2x ( divide both sides by 2 )
16 = x → c
