The sum of a number plus 3 to the square root of 9 to the sum of 2 would equal -2. This is a math problem.
2
(x + 3)2 = (x + 2)2 + 9 x2 + 6x + 9 = x2 + 4x + 4 + 9 2x = 4 x = 2
on the top right part of the number being squared and remember to make it smaller than the number being squared
(x + 3)^2 - 13 = (x + 2)^2 x^2 + 6x + 9 -13 = x^2 + 4x + 4 x^2 + 6x - 4 = x^2 + 4x + 4 6x - 4x = 4 + 4 2x = 8 x = 4
150 millimeters squared is more.
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.

a number equals 2
If you mean: (x+3) squared = (x+2) squared +11 Then the value of x works out as 3
if it is not this . -3<x<-2 < or equal
