If X equals -1 and y equals 2 what does 2x3-3xy equal?
x = -1 y = 2 2x3 - 3xy = 2 (-1)3 - 3(-1)(2) = 2 (-1) - (-6) = -2 + 6 = 4 Suggestion: Please be careful around problems like this until you have some more experience.
What is the value of 3xy plus 4y3 and y equals 2 the expression below when x equals 5?
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.

yes 3xy=6
What is 3xy minus 3xy?
3xy - 3xy = 0
X2 plus 3xy - 18y2 equals?
(x + 6y)(x - 3y)
What are M and Y if Y plus y plus y plus equals MY?
M=3 because y+y+y= 3xY and MY= MxY
What are the terms of 4xy 3xy-3xy 2xy?
The expression (4xy - 3xy + 2xy) consists of three terms: (4xy), (-3xy), and (2xy). Each term is a product of the coefficient (a number) and the variable part, which in this case is (xy). The coefficients are 4, -3, and 2, respectively. To combine the like terms, you would simplify the expression to ( (4 - 3 + 2)xy = 3xy).
