</h2>
Any polygon that has exactly 3 sides is called a triangle. Here you haven't provided any figure, so I'll assume that we have two triangles as indicated in the figure below. As you can see, we have two sides:
When placing together we realize that those sides measures the same, so:
So 
is the diagonal of the shape. From the figure we also know that opposite sides are equal and parallel, therefore, this shape represents a parallelogram. Remember that a parallelogram is a quadrilateral where both pairs of opposite sides are parallel.
<em>So correct option is:</em>
<em>Parallelogram</em>
C.
Observe that the roots of polynomial are 
We have a polynomial in a factored form,
If you substitute x for any of the product will always equal to zero that is these numbers are roots of polynomial.
Hope this helps :)
The function is:
f ( x ) = 1,000 · 2^x
x is the number of weeks.
1. y - intercept is : y = 1,000.
2. The y-intercept represents the cicada population at the start ( for x = 0 ).
f ( 0 ) = 1,000 · 2^0 = 1,000 · 1 = 1,000.
3. The 2 in the function shows that cicada population doubles every week.
The answer to thid question is 0.8
