Answer:

l = 14

Step-by-step explanation:

Given

p = 2l + 2w and w = 7, p = 42, substitute values into formula

42 = 2l + (2 × 7), that is

42 = 2l + 14 ( subtract 14 from both sides )

28 = 2l ( divide both sides by 2 )

14 = l or l = 14

Como identifico una X Cubica en un polinomio

Nadya [2.5K]

la componente "cubica" será aquella que tenga un exponente igual a 3.

<h3>¿como identifico una X Cubica en un polinomio?</h3>

Un polinomio tiene la forma general:

$p(x) = a_n*x^n + ... + a_1*x^1 + a_0$

Donde todos los exponentes de x son numeros naturales.

Particularmente, la componente "cubica" será aquella que tenga un exponente igual a 3.

Entonces, por ejemplo, en:

$p(x) = 4*x^5 + 2*x^4 + 5*x^3$

La parte cubica será:

$5*x^3$
