Se han dividido tres varillas de hierro de 160cm, 180cm y 200cm, en trozos de igual longitud, los mas largos posibles, sin que sobre hierro. ¿Cual es la longitud de cada trazo?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
