-2
An expression that equals -5 could be represented as ( x - 10 ) when ( x = 5 ). Another simple example is ( -2 + (-3) ), which also equals -5. Additionally, the equation ( 3 - 8 ) yields -5.
One possible expression is [ 1/(x - 4)+ 1/x ].
To determine the value expression when ( x = -2 ), you need to substitute -2 into the given expression. For example, if the expression is ( 2x + 3 ), substituting -2 gives ( 2(-2) + 3 = -4 + 3 = -1 ). The specific value will depend on the expression you have; please provide that for a more accurate answer.
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
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.

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
An expression that equals -5 could be represented as ( x - 10 ) when ( x = 5 ). Another simple example is ( -2 + (-3) ), which also equals -5. Additionally, the equation ( 3 - 8 ) yields -5.
(x - 4)(x^2 + 4x + 16)
One possible expression is [ 1/(x - 4)+ 1/x ].
To determine the value expression when ( x = -2 ), you need to substitute -2 into the given expression. For example, if the expression is ( 2x + 3 ), substituting -2 gives ( 2(-2) + 3 = -4 + 3 = -1 ). The specific value will depend on the expression you have; please provide that for a more accurate answer.
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
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.
