Question

If ( 28 - x) is the mean proportional of ( 23 - x) and ( 19 - x) then find the value of x​

Answer 1

Answer:

x = 347/14

Step-by-step explanation:

23 - x / 28 - x = 28 - x / 19 - x

i.e., (23 − x)(19 − x) = (28 − x)2

x^2 − 42x + 437 = 784 − 56x + x^2

56x − 42x = 784 − 437

14x = 347

x = 347/14
