Answer:
option A by symmetry of figure.and then using formula of triangle and rectangle.
Answer:
y= (-2+4x)/3
x= (-2+3y)/4
Step-by-step explanation:
for y;
![3y = - 2 + 4x](https://tex.z-dn.net/?f=3y%20%3D%20%20-%202%20%20%2B%204x)
![y = \frac{ - 2 + 4x}{3}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B%20-%202%20%2B%204x%7D%7B3%7D%20)
for x;
![- 4x = 2 - 3y](https://tex.z-dn.net/?f=%20-%204x%20%3D%202%20-%203y)
![- x = \frac{2 - 3y}{4}](https://tex.z-dn.net/?f=%20-%20x%20%3D%20%20%5Cfrac%7B2%20-%203y%7D%7B4%7D%20)
multiply both sides by minus
![- ( - x) = - ( \frac{2 - 3y}{4} )](https://tex.z-dn.net/?f=%20-%20%28%20-%20x%29%20%3D%20%20-%20%28%20%5Cfrac%7B2%20-%203y%7D%7B4%7D%20%29)
![x = \frac{ - 2 + 3y}{4}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%202%20%2B%203y%7D%7B4%7D%20)

1. True
2.False <span>A </span>rhombus<span> is quadrilateral with all side of equal length. Thus a quadrilateral with all sides of equal length and all </span>angles right angles<span> is still a </span>rhombus<span> but it is also a square. It is also a quadrilateral, a rectangle and a parallelogram. A square is a special kind of </span>rhombus<span>, but it is still a </span>rhombus<span>.
