What is 4x 3y -5x 2y?
The expression 4x - 3y - 5x - 2y can be simplified by combining like terms. Like terms have the same variables raised to the same powers. In this case, the x terms are like terms and the y terms are like terms. Combining the x terms, we get -x, and combining the y terms, we get -5y. Therefore, the simplified expression is -x - 5y.
How do you simplify x plus x plus x plus x plus y plus y plus y plus x?
To simplify the expression "x + x + x + x + y + y + y + x," you can first combine like terms. Group the x terms together and the y terms together. This gives you 4x + 3y. So, the simplified form of the expression is 4x + 3y.
What is X squared minus y squared divided by x minus y?
(x^2 - y^2) / (x - y) Apply the difference of squares formula: (x + y)(x - y) / (x - y) Assuming x is not equal to y, we can cancel terms leaving x + y When x = y, the denominator becomes 0, and the equation gives no information.
What is X squared - Y squared divided by X-Y?
The expression (X^2 - Y^2) / (X - Y) can be simplified using the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). Applying this formula, we get (X + Y)(X - Y) / (X - Y). The (X - Y) terms cancel out, leaving us with the simplified expression X + Y. Therefore, (X^2 - Y^2) / (X - Y) simplifies to X + Y.
What are the numbers whose sum is 64 and whose differences is 42?
