Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

\frac{5}{5}= \frac{-2y-10}{5}

x= \frac{-2}{5}y-2

2-  3x+y+−y=66+−y

3x=−y+66

\frac{3x}{3} = \frac{-y+66}{3}

x=\frac{-1}{3}y+22

Step-by-step explanation:

Square and Rhombus are the following quadrilaterals have diagonals that are always  perpendicular to each other.

C. Square

D. Rhombus

<u>Step-by-step explanation:</u>

This implies the diagonals of a square and rhombus are perpendicular. The diagonals of a square and rhombus are a similar length. In elementary geometry, the property of being opposite is the connection between two lines which meet at a right angle. The property stretches out to other related geometric items.  

Principally Perpendicular lines will be lines that cross at a right (90 degrees) edge. so when it goes under shape rhombus and square have the equivalent of a considerable number of sides parallelly.
