What is the following product?
-Dominant- [34]

Answer:

98 - 40√6

Step-by-step explanation:

We have to simplify the following product :

(5\sqrt{2} - 4\sqrt{3})(5\sqrt{2} - 4\sqrt{3}).

Now, (5\sqrt{2} - 4\sqrt{3})(5\sqrt{2} - 4\sqrt{3})

= (5\sqrt{2} - 4\sqrt{3})^{2}

= (5\sqrt{2})^{2} - 2 (5\sqrt{2}) (4\sqrt{3}) + (4\sqrt{3} )^{2}  

{Since we know the identity (a - b)² = a² - 2ab + b² }

= 50 - 40√6 + 48

= 98 - 40√6 (Answer)

If a point P(–1, –1) is reflected across the line y = –2, what are the coordinates of its reflection image?
Ksivusya [100]
Since the line of refrection is a horizontal line, the x-coordinate of the image will be the same as the x-coordinate of the point P(-1, -1). P(-1, -1) is one unit above the line y = -2, hence the image will be one unit below the line y = -2. Therefore the coordinate of the image is (-1, -3)
