The variable is d, in the algebraic expression 7d+2
It is: d
8
The coefficient would be the number multiplied by the variable, in this case: 7
The coefficient of 3+7d is 7
The variable is d, in the algebraic expression 7d+2
It is: d
8
The coefficient would be the number multiplied by the variable, in this case: 7
The coefficient of 3+7d is 7
7 is the coefficient of the variable d
2
7d + 2 7 is the only coefficient
what is the constant in algebraic experssion 7d+2
d is the variable here.
The expression simplified is: 7d-2cd-5c
By definition a term is the basic unit of algebra which must contain 3 parts - a sign, a coefficient and a variable (e.g., 2n [+ sign implied, coefficient '2' and variable 'n'] and -7d). In the expression 2n-4-7d then, there are 2 terms.
