What does this mean

two multiple two point and three point baskets ?

$$\sqrt{275}=\sqrt{25}\times \sqrt{11}=5\sqrt{11}$$

That would depend on your actual question, usually you need either a scientific calc or a Tan table sheet :)

So what is your question?

What does this mean

If is the result of the transformation of under D2 ° T– 4,3               

Well it is right and it is written but it is not write because that doesn't make any sense 

The area is how many squares of a certain size will fit inside a flat (plane) shape.

Sorry MathsGod but that is not correct.

The total area is   $$1865 cm^2$$    THAT IS NOT  $$1865^2$$    !!!!

1)  If the sides of a square are 8cm  What is the area of that square ?

2)  If the area of a squara is 25cm^2 .   What is the length of the side?

$$\begin{array}{rlll}
\frac{3}{x^3-12x^2+48x-64}+\frac{111}{64-x^3}&=&0\qquad&(1)\\\\
\frac{3}{x^3-3(4x^2)+3(4^2x)-4^3}+\frac{111}{-(x^3-64)}&=&0\qquad&(2)\\\\
\frac{3}{(x-4)^3}-\frac{111}{x^3-64}&=&0\qquad&(3)\\\\
\frac{3}{(x-4)^3}-\frac{111}{(x-4)(x^2+4x+16)}&=&0\qquad&(4)\\\\
\frac{3(x^2+4x+16)}{(x-4)^3(x^2+4x+16)}-\frac{111(x-4)^2}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(5)\\\\
\frac{3x^2+12x+48}{(x-4)^3(x^2+4x+16)}-\frac{111(x^2-8x+16)}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(6)\\\\
\frac{3x^2+12x+48}{(x-4)^3(x^2+4x+16)}-\frac{111x^2-8*111x+16*111}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(7)\\\\
\frac{3x^2+12x+48}{(x-4)^3(x^2+4x+16)}+\frac{-111x^2+888x-1776}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(8)\\\\
\frac{-108x^2+900x-1728}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(9)\\\\
\frac{-36(3x^2-25x+48)}{(x-4)^3(x^2+4x+16)}&=&0\qquad&(10)\\\\
x&=&\frac{25\pm 7}{6}\qquad \qquad&(11)\\\\
\end{array}$$

(11) came from the quadratic formula

NOW which line do you need explained?

Use.   atan
