What are the coefficients of x in the expression 8 – x + y?
What are the coefficients of y in the expression 4x – 3y?
coefficient is the integral number next to a given variable.
for y, it is 3
What are the coefficients of y in the expression yz^{2}+ 5?
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. So here the coefficient is z^{2}.
Write the expression for the statement: the sum of three times x and 11.
Three times of x is 3 multiplied by x which is 3x . sum of 3x and 11 is 3x plus 11 which is 3x + 11
Write an expression : Raju s father s age is 5 years more than 3 times Raju s age. If Raju s age is x years, then father’s age is
Since father’s age is 3 times Raju's age and 5 more . So three times is 3x and 5 more, so it means 3x+5 is the answer.
Number of terms means the total number of individual elements present in a statement.
We have 4p^{2}q, 3pq^{2} and 5 separated by a plus or minus sign, so these three are our terms.
The expression for sum of numbers a and b subtracted from their product is
Sum of numbers is (a+b) , its product is ab and we have to subtract sum from product , so its ab(a+b)
mn+5 – 2 + mn + 3 = mn + mn + 5  2+3 = 2mn+6
