Si la hipotenusa de un triángulo rectángulo mide 2cm y uno de sus lados mide 1cm, ¿Cuánto mide el otro lado? Calcular la altura que podemos alcanzar con una escalera de 3 metros apoyada sobre la pared si la parte inferior la situamos a 70 centímetros de ésta.

Al atardecer, un árbol proyecta una sombra de 2,5 metros de longitud. Si la distancia desde la parte más alta del árbol al extremo más alejado de la sombra es de 4 metros, ¿cuál es la altura del árbol?

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
