The formula states that:
Faces + Vertices - Edges = 2
So 21 + V - 49 = 2 => V = 2+49-21 = 30
Answer A!
Answer:
D
Step-by-step explanation:
As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.
Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)
The option A is incorrect due to the same problem for the point (8,7)
The correct option is D.
<span>−24x<span>y^5</span>−15x×3<span>y^2</span>+9x×2<span>y<span>^3
</span></span></span><span><span>−24x<span>y<span>^5</span></span>−45x<span>y^<span>2</span></span>+9x×2<span>y^3</span></span><span>
