Answer:
number is 500 hope this helps
Answer:
125
Step-by-step explanation:
Find the surface area of the table that Raj wants to cover.
Since the side table is a cube each side is identical.
Step 2:
Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.
Step 3:
Find the surface area of each tile.
The surface area of each tile is 6 · 6 = 36 square inches.
Step 4:
Find the number of tiles needed to cover the table.
4,500 square inches
36 square inches per tile
= 125 tiles
Raj will need 125 tiles to cover the table.

I'm going to put this into vertex form, which is y=a(x-h)^2+k
To do this, you use completing the square. Start by subtracting 1 from each side
-1+y=x^2+2x
Then, divide b (2) by 2 and square it. Add that number to each side. (normally when you complete the square, you take out the gcf of the right side of the equation before you do this. Then, you would multiply (b/2)^2 by the gcf before adding it to the left side. Since there is no gcf, we do not have to worry about this)
2/2=1
1^2=1
-1+1+y=x^2+2x+1
Next, simplify the left side and factor the right side.
y=(x+1)^2
This is vertex form. a=1, h=-1, and k=0
The vertex is (h,k) so it is (-1,0)
