The coefficient of 8 • 2N is _____.
lesantik [10]

Answer:

16 is the coefficient of N.

Step-by-step explanation:

Coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables. The coefficients of an algebraic term can be positive or negative, and this multiplies the unknown term.

For example:

In 2a, 2 is the coefficient of a;

In x, 1 is the coefficient of x but it is not visible;

In 2/3p, 2/3 is the coefficient of p;

In -3f, -3 is the coefficient of f;

In 3 × 6t, 18 is the coefficient of t.

Variable is a symbol, commonly a single letter, that represents a number, called the value of the variable, which is either arbitrary, not fully specified, or unknown. Making algebraic computations with variables as if they were explicit numbers allows one to solve a range of problems in a single computation. A typical example is the quadratic formula, which allows one to solve every quadratic equation by simply substituting the numeric values of the coefficients of the given equation for the variables that represent them.

So,

In 8 × 2N, 16 is the coefficient of N ( 8 × 2 = 16)

N is the variable.

A new outdoor recreation center is being built in Hadleyville. The perimeter of the rectangular playing field is 316 yards. The
algol13

Given :

Perimeter of rectangular filed , P = 316 yards.

The length of the field is 4 yards less than twice its width.

To Find :

The dimensions of the playing field.

Solution :

Let, width be x.

So, by given condition length will be 2x - 4.

Perimeter is given by :

P = 2( l + b )

316 = 2( 2x - 4 + x )

3x - 4 = 158

x = 54 yards.

So, the dimensions are 54 yards and 104.

Hence, this is the required solution.
