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
Well, honey, the coefficient of 7h is 7, and the coefficient of 3 is 3. So, technically, the coefficient of 7h plus 3 is just 7. But hey, don't stress too much about it - math is just a fancy way of saying "I can solve problems better than you!"
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.
