Rectangle:
If each angles of a quadrilateral is 90 and opposite side are equal then it is a rectangle.
Rhombus:
If in a quadrilateral, opposite angles are equal and all sides are equal, then it is a Rhombus
The answer I got was (1,4)
Answer:
h= −15 /2
Subtract 6h from both sides.
Subtract 7 from both sides.
Divide both sides by 2.
The answer would be the first one.
I find it easier to expand the equation (you still get the same answer).
= 2 * 7x + 2 * 3y + 2 * 3
= 14x + 6y + 6
Hope this helps!
There are no real roots for a negative number, so -81 has no real roots, if the number is 81 however, then the tow roots are 9
