1 answer:

7 0

Multiply everything in the second parenthesis by x.

-3x^3 + 3x^2 + x

Multiply everything in the second parenthesis by 2.

-6x^2 + 6x + 2

Combine these two equations together.

-3x^3 + 3x^2 + x - 6x^2 + 6x + 2

Combine like terms.

-3x^3 - 3x^2 + 7x + 2

Hope this helps!

olchik [2.2K]

Answer:

There are 1849 tiles on the whole wall.

Step-by-step explanation:

If there are 85 tiles along the two diagonals, we can use the following rule:

$\frac{85+1}{2}=43$

So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.

Now, as we have a square the side will have 43 tiles so the total area will be cover with:

$A=43*43=1849$

Therefore, there are 1849 tiles on the whole wall.

I hope it helps you!
