△ABC is an isosceles triangle. Each horizontal line is the bisector of two sides of a triangle. How long is MN¯¯¯¯¯¯¯? Triangle A B C. Side A C is horizontal and is 12 centimeters long. Four other horizontal segments are drawn inside the triangle creating increasingly smaller similar triangles. From bottom to top the segments are, starting on side A B and ending on side B C: segment D E, segment F G, segment H K, and segment M N.

MN = { }cm

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
