3 + z
All variables if they have no visible coefficient have an implied coefficient of 1.
The coefficient of 3+7d is 7
The coefficient is the number that multiplies a value. For example, the coefficient of 4x is 4. If n+3 is in brackets in the form (n+3) then the coefficient is one. If not the the coefficient of n is also 1.
(z + 15)(z + 3)
2z + 5 - xz
In the expression 7h + 3, the coefficient of the variable h is 7. Coefficients are the numerical factors in front of variables in a term. In this case, the coefficient is 7 because it is the number directly multiplied by the variable h. The constant term 3 does not have a variable attached to it, so it is not considered a coefficient.
There is no single coefficient for that equation, as a coefficient is the number by which any term is multiplied. The coefficients in that equation are 5, 2, 4 and 3.
The coefficient of 3+7d is 7
5 and 7 are two coefficient. And that is all. There is no third coefficient.
The coefficient is the number that multiplies a value. For example, the coefficient of 4x is 4. If n+3 is in brackets in the form (n+3) then the coefficient is one. If not the the coefficient of n is also 1.
6 is the coefficient of n in this expression.
The coefficient is 6.
