7*(2*x - 16), or maybe 7*| 2*x - 16 |. It depends on if you want to keep the 'difference' to be a positive number.
L = S + 16; 3 x (S + 16) = 9S ie 3S + 48 = 9S ie 48 = 6S so S = 8 and L = 24
Your answer is 52. The reason for this is because the difference between 7 and 10 is 3. The difference between 10 and 16 is 6. The difference between 16 and 28 is 12. So the last one must be 28 +24 = 52
The square of number is a *a ( a number times itself ). For example, 4*4=16, so the square of 4 is 16. the square root is the number before you square it. The square root of 16 is 4. It actually simple to remember this way: think of the root as the root of a tree, growing to multiply itself.
