Question

If (x+6) is the mean proportion between (x+4) and (x+10) . find the value of 'x'​

Answer 1

Answer:

x = 2

Step-by-step explanation:

Given (x+6) is the mean proportion between (x+4) and (x+10)

(x+6)^2 = (x+4)(x+10)

x^2 + 12x + 36 = x^2 + 10x + 4x + 40

12x + 36 = 1 4x + 40

14x-12x = 40-36

2x = 4

x = 2
