X2 (5)2 = 25 (- 5)2 = 25 An identity, almost, as any number put into this expression will yield the same value.
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.

Well, darling, 2x plus 5 is just an algebraic expression that represents the sum of 2 times a variable x and 5. So, if you want to find the value of that expression, you need to know the value of x. Math can be a real hoot sometimes, can't it?
