Question

Find the value of x so that: 5, 15, X, X + 8 are proportional.​

Answer 1

Answer:

We know that

Product of Extreme = Product of Means

Extremes is = 5 and x + 8

Means is = 15 and x

=. 5(x+8) = 15x

= 5x + 40 = 15x

= 40 = 15x-5x

= 40= 10x

=. - 10x = - 40

= 10x = 40

= x = 4

Now check

= 5, 15, 4, 12

= 5 × 12 = 15 × 4

= 60 = 60
