What are the two kinds of coefficients?
In terms of mathematics, a coefficient plays the role of a multiplicative factor in a series or an expression. The two different kinds of coefficients include numbers and letters.
What do coefficients stand for?
Coefficients don't 'stand' for anything. They are numbers which multiply variables. For instance, in the expression 3 x + 2, three is the coefficient of x.
Which expression is equivalent to -28xy 35y?
To find an expression equivalent to -28xy 35y, we can first simplify by multiplying the coefficients -28 and 35 to get -980. Then, we multiply the variables x and y to get xy^2. Therefore, the expression equivalent to -28xy 35y is -980xy^2.
What is the answer to 4e plus 3d plus 5e-5d?
The expression 4e + 3d + 5e - 5d can be simplified by combining like terms. Grouping the terms with the same variable together, we have 4e + 5e + 3d - 5d. Combining the coefficients of e gives us 9e, and combining the coefficients of d gives us -2d. Therefore, the simplified expression is 9e - 2d.
What is 2x plus 3y plus 4x plus 9y?
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
