The perimeter of the pentagon is 62 units find the length of side BC

1 answer:

7 0

recall that the perimeter is simply the sum of all outer sides of a figure.

$\bf 12+3x+10+(x+1)+(2x+3)=62\implies 6x+26=62 \\\\\\ 6x=36\implies x=\cfrac{36}{6}\implies \boxed{x=6} \\\\\\ BC=(6)+1\implies BC=7$

Answer:

x = (ab +a +b +c)/(a +b)

Step-by-step explanation:

Eliminate parentheses, subtract left terms not containing x, divide by the coefficient of x.

$a(x-b)+bx-c=a+b\\\\ax+bx-ab-c=a+b\\\\x(a+b)=ab+a+b+c\\\\\boxed{x=\dfrac{ab+a+b+c}{a+b}}$
