The variable is d, in the algebraic expression 7d+2
The variable is "d".
7 is the coefficient of the variable d
The coefficient would be the number multiplied by the variable, in this case: 7
7d + 2 7 is the only coefficient
The variable is d, in the algebraic expression 7d+2
The variable is "d".
7 is the coefficient of the variable d
what is the constant in algebraic experssion 7d+2
The coefficient would be the number multiplied by the variable, in this case: 7
7d + 2 7 is the only coefficient
2
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.
It is an expression of algebraic terms with no equality sign
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
d is the variable here.
Algebraic expressions are mathematical phrases that contain numbers, operations and at least one variable. An example of an algebraic expression would be : 4x + 3= 9x.
