Question
a rectangle has a length of (3x - 4) units and a width of (2x + 3) units. what is the perimeter of the rectangle in terms of x? a. (5x - 2) units b. (5x + 14) units c. (10x - 2) units d. (10x + 14) units
Step1: Escribir la fórmula del perímetro
El perímetro $P$ de un rectángulo se calcula como $P = 2(l + w)$, donde $l$ es la longitud y $w$ es el ancho. Aquí, $l=3x - 4$ y $w = 2x+3$.
Step2: Sustituir valores en la fórmula
$P=2((3x - 4)+(2x + 3))$.
Step3: Simplificar dentro de los paréntesis
$P=2(3x-4 + 2x+3)=2(5x - 1)$.
Step4: Distribuir el 2
$P = 10x-2$.
