What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
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.
What is 2x plus 5?
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?

What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
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.
What is the value of n in the expression x cubed plus nx squared plus 3x -5 when divided by x -2 with a remainder of -3 showing brief details of your work?
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

What is the value expression if x equals -2?
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.

How would you calcullat -3x-2?
To calculate the expression (-3x - 2), you need to know the value of (x). Once you have that value, substitute it into the expression. For example, if (x = 1), then (-3(1) - 2 = -3 - 2 = -5). The final result will depend on the specific value of (x) you are using.
