3. Margo has drawn a parallelogram and is giving you clues about it for a guessing game. If her first clue is that the parallelogram has 4 congruent sides but does not have congruent
diagonals, which parallelogram could Margo have drawn?
A Trapezoid
B. Rhombus
C Rectangle
D. Square

B) Rhombus

Step-by-step explanation:

4 congruent sides is either a square or a rhombus

a square has congruent diagonals but a rhombus does not

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

5x+10 is the correct one
