Answer:

Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
=
-
← subtract numerators leaving the common denominator
= 
= 
=
← cancel common factor (y - 1) on numerator/denominator
= 
Hello,
Answer C : always Al Kashi
Hey there!
Here is your answer:
<u><em>The proper answer to this question is "2×10^6".</em></u>
Reason:
<u><em>Translate these equations in standard from:</em></u>
<u><em>2×10^6=2,000,000 </em></u>
<u><em>9×10^5=900,000</em></u>
<u><em>2,000,000≥900,000</em></u>
<em>Therefore 2×</em><span><em>10^6 is greater!</em>
If you need anymore help feel free to ask me!
Hope this helps!

When you have to describe a 3D shape you have to keep the following definitions in mind:
<em>1. The face of a 3D shape is a flat surface.</em>
The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.
<em />
<em>2. The edge is where two faces meet.</em>
For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.
<em>3. The vertex is a corner, where the edges meet.</em>
There are three vertices on each end of the shape, so it has a total of 6 vertices.
A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.
