The expression (4xy) represents a monomial where 4 is the coefficient and (xy) is the product of the variables (x) and (y). It indicates that the value of the expression is obtained by multiplying 4 by the values of (x) and (y). This expression is often used in algebra to represent relationships in equations or to describe quantities in various mathematical contexts.
Without an equality sign the given expression is not an equation
It stays the same because it does not have any common terms. A: 6y-4xy
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
It is 4xy.
2xy
A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4xy).
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
Without an equality sign the given expression is not an equation
3x2y - 4xy + 4x
4xy
It stays the same because it does not have any common terms. A: 6y-4xy
4xy/0.25x = 16y
The GCF is 2x.
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
It is 4xy.
2xy
To multiply 2x by 2y, you would use the distributive property of multiplication over addition. This means you would multiply each term in the first expression by each term in the second expression. In this case, 2x * 2y would result in 4xy, as 2 * 2 equals 4 and x * y equals xy.
