Given each set of vertices, determine whether parallelogram ABCD is a rhombus, a rectangle, or a square. A(-2,6), B(-2,1), C(-9,1), D(-9,6)

b i think

step-by-step explanation:

not really sure

11

step-by-step explanation:

32.50-7.50=25

225/25=11

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
