Write and solve an equation to find the unknown side length x (in centimeters) perimeter = 12 cm
an equation is | | = 12
the unknown side length is | | centimeters

sorry its my first time on i need help

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)

answer: 1, 3 and 5 are correct

step-by-step explanation:

a rotation about point l
