I see you want to solve -2x + y + 6 = 0 2x + y - 8 = 0 simultaneously. Next time, please put each equation on its own line, like this:
-2x + y + 6 = 0
2x + y - 8 = 0
or separate the two equations with "and" or some other symbol.
We can easily eliminate x by adding these 2 equations together:
-2x + y + 6 = 0
2x + y - 8 = 0
-------------------
2y - 2 = 0, which yields y = 1. This is the equation called for in this problem. You were not asked to find x.
We can solve for the surface area of the triangular prism using the formula below:
SA=bh + (s1+s2+s3) H
where b for the base, h and H for the height while s1, s2 and s3 for the length of the sides of the equilateral triangles.
Solution is shown below:
SA=10*9+(10*10*10) *18
SA=90+(1000*18)
SA=1,620,000 u²
The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.
The given polynomial is

Hello! Remember you have to write complete questions in order to get good and exact answers. This question is incomplete but I'm going to help you assuming some things:
- The small rectangle is built up by the x and y-axis and the point

- The large rectangle is built up by the x and y-axis and the point that follows the rule:

For the small rectangle, the vertices are:

Therefore, if
lies on the small rectangle, for the large rectangle we have:

In conclusion:
If point
lies on the small rectangle, then
lies on the large rectangle.
