Question

anyone know the answer?

Answer 1

Step-by-step explanation:

x^2+4x^2+9x^2=224

so x=4

so a=4

b=8

c=24

so difference between square of greater and least number

24-4=20

Answer 2

Answer:

option b 128

Step-by-step explanation:

let's say those numbers are x, 2x, 3x

so sum of their squares =x^2+4x^2+9x^2=14x^2

but according to the given info

14x^2= 224

x^2=224/14=16

so x=4

so the numbers are

4,8,12

so the difference of squares of greatest and least =12^2-4^2=144-16

=128
