<h3>¿Qué e el perímetro?</h3>
Es la suma total de los lados del triángulo, en este caso el perímetro total es de 80.
<h3>¿Cómo calcular las dimensiones del triángulo?</h3>
Se pueden calcular usando el total y la información sobre cada lado:
- x+4 + 3x+2 + 2x-2 = 80
- 6x + 4 = 80
- 6x = 80 - 4
- 6x = 76
- x = 76/ 6
- x = 12.66
Finalmente calcule cada lado:
- A. x+4 = 12.66 + 4 = 16.66
- B. 3x + 2 = 3 x 12.66 + 2 = 39.98 o 40
- C. 2x - 2 = 23.32

Y= -1/2x -1
first use the formula y2-y1/ x2-x1
then plug in (-10, 4) and (-16, 7) into the formula so it should look like 7-4/ -16 +10
that should simplify down to -1/2
Next plug one of the points into the new formula y=-1/2x +b to find B
