Answer:
perpendicular bisectors of each other
Step-by-step explanation:
For a quadrilateral to be rhombus the diagonals have to be <em><u>perpendicular bisectors of each other</u></em>.
__
The diagonals of a parallelogram bisect each other. When that parallelogram is a rhombus, the diagonals are perpendicular, hence mutual perpendicular bisectors.
Answer:
first number is 4
second number is 0
Step-by-step explanation:
y = 1st number
x = 2nd number
system of equations:
5y + 4x = 20
4y + 2x = 16
I multiplied the second equation by -2 to eliminate the 'x-values'
-2(4y + 2x = 16) = -8y - 4x = -32
now add to 1st equation: <u>5y + 4x = 20</u>
-3y = -12
y = 4
solve for 'x':
5(4) + 4x = 20
20 + 4x = 20
4x = 0
x = 0
