Question

If x + 7 is the mean proportional between (x+3)
and (x +12), find the value of x.​

Answer 1

Answer:

0

Step-by-step explanation:

x+7=(X+3+X+12)÷2

2X+14=2x+15

14=15 which is not possible so X=0

Answer 2

Step-by-step explanation:

x +7 = (x+3+x+12)÷2

2x + 14 = 2x + 15

14 = 15

So, x = 0
