Question

(5-x) (x+8) what cofficent value of x

Answer 1

Answer:

- 3

Step-by-step explanation:

The given expression is (5 - x)(x + 8).

Concept:

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.

Calculation:

(5 - x)(x + 8).

= 5(x + 8) - x(x + 8).

= $5x + 40 - x^{2} - 8x$

= $-x^{2} - 3x +40$

Hence, the coefficient of x in (5 - x)(x + 8) is -3.
