The coefficient of 3+7d is 7

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.

7

It would be: 3(7-d) as an algebraic expression

A variable is a letter that represents a number. A n expression that contains at least one variable is called a variable expression or an algebraic expression.A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables.An algebraic expression consisting of only one term is called a monomial (3x, xy, 2y, xyz); of two terms is called a binomial (x + y, x^2 - 1, a + 2b); of three terms is called trinomial (x + 2y - 4, 3x^2 + 2xz +3). In general, an algebraic expression consisting of two or more terms is called a polynomial

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.

The coefficient in an expression is the multiplier of the variable in the equation. Here, the coefficient would be 6.

Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
