Answer:
3) (0, 0)
4) (-1, 2)
Step-by-step explanation:
I find a graphing calculator provides a quick solution to a system of linear equations.
3) The solution is (x, y) = (0, 0)
4) The solution is (x, y) = (-1, 2)
__
In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.
Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ():
The triangle's area ():
Now add up all the sides. (3 Rectangles, 2 Triangles.)
The total surface area is 350.82 cm squared.
