6x -5y plus -3x -4y simplify and solve rational expressions?
That simplifies to 3x - 9y. It can't be solved since it doesn't equal anything.
Is yx squared 3x 1a function?
No. There is no equality (or inequality) in the question: only a list of expressions.
What operations are involved in the expressions 2x plus 7 and 3x plus 6?
Multiplication and addition.
What is 2x with the exponent 2 plus 3x plus 1. what is 7n with the exponent 2 plus 9n plus 2. what is 3x with the exponent 2 plus 8x plus 5. what is 7y with the exponent 2 plus 19y plus 10?
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
What is 3x times x?
There are no expressions given in the question.Otherwise, there are infinitely many possible expressions. Any expression of the from 3x*y/y where y is any non-zero constant or function - of x or other variables - will be equivalent.
Simplifying rational expressions 6x-5y plus -3x-4y?
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
6x -5y plus -3x -4y simplify and solve rational expressions?
That simplifies to 3x - 9y. It can't be solved since it doesn't equal anything.

When are the expressions 3x 12 and 3(x 4) equivalent Explain how you know?
Expand the bracket.

Multiplication and addition.
Is yx squared 3x 1a function?
No. There is no equality (or inequality) in the question: only a list of expressions.
Which expressions are equivalent to 3 x?
There's not enough information here to answer this accurately. One problem is the lack of operation indication. This could be 3x or 3x or 3 - x or 3 + x. In the future, it is better to write out operations on this website. Presumably, you were given a set of expressions to compare that to but you didn't include them. One possibility: x + x + x = 3x
Two linear expressions with a sum of -5x plus 4?
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
How the difference of two squares rule can be used to factorise an expression?
For example: 9x2-25 = (3x-5)(3x+5) but this only applies to negative expressions it wouldn't apply to 9x2+25
Expand 3(x plus 4)?
You simply multiply the expression on the outside (in this case, 3) by each of the expressions inside the parentheses, and add everything up. In this case, 3x + 3 times 4.
What is this 3x equals 2y plus 7 in standard form?
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
