Answer:
At first we should know that:
<u>The properties of the square are:</u>
- It has four equal sides.
- All angles are right angles or equal to 90º.
- The sum of its all angles is 360º
- It has two pairs of perpendicular lines.
- It has two pairs of parallel lines.
<u>The properties of Rhombus</u>
- It has equal four sides.
- The opposite sides are of the same length.
- It has two acute angles and two obtuse angles.
- The sum of its all angles is 360º
- It has zero pairs of perpendicular lines.
- It has two pairs of parallel lines.
So, Wade is incorrect because the quadrilateral may be <u>Rhombus</u>
And the quadrilateral to be a square, she needs to show that It has two pairs of perpendicular lines.
Direct variation:-
y = kx where k is a constant
y=12 when x=6 so we have:-
12 = k*6
k = 12/6 = 2
so our equation of variation is y = 2x Answer
The formula for strontium phosphide is Sr3(PO4)2.
Hopefully this helps! :)
