point d is on segment bc. segment bc measures 8x units in length. what is the length of segment bc? units c d b 3x + 8 4x + 10

Answer

Explanation:

Step1: Establecer la ecuación

Como $BC = CD+DB$, entonces $8x=(3x + 8)+(4x + 10)$.

Step2: Simplificar la ecuación

Combinar términos semejantes: $8x=3x+4x + 8+10$, es decir $8x=7x + 18$.

Step3: Resolver para x

Restar $7x$ de ambos lados: $8x-7x=7x + 18-7x$, lo que da $x = 18$.

Step4: Encontrar la longitud de BC

Sustituir $x = 18$ en la expresión para $BC$ que es $8x$. Entonces $BC=8\times18 = 144$.

Answer:

144
