If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
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?
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.

Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3

When x = 2, 4x3 = 32
Since there is no expression given, there is no sensible answer.

4x^2 + 9 is a prime algebraic expression. Its numerical value may be prime of not - depending on the value of x.For x = 1, the value of the expression is 13 - a prime whereasfor x = 2, the value of the expression is 25 - not a prime.
n is a variable (representation of the number you are trying to find. 4n means 4 x n. EXAMPLE: If n = 2, then 4n = 4 x 2 = 8
It would help if the expression was given!

If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
sqrt(x+6) is an expression that can't be simplified.It's a number, whose value depends on the value of 'x'.
