3 0

Answer:

(2,3) or x=2 and y=3

Step-by-step explanation:

find x...

3x-6y= -12

3x = 6y-12

x = 2y-4

plug x into the other equation

6(2y-4) + 6y = 30

12y-24 +6y = 30

18y = 54

y = 3

Plug y into an equation to find x

3x-6(3) = -12

3x-18= -12

3x=6

x=2

[Answer] y=3 and x=2 or (2,3)

I need to find the surface area of this
solmaris [256]
We need to find surface area, so we can imagine breaking it up into face net.

There will be 18 × 18 square base, four 18 × 40 rectangles, and four triangles with base 18 and height 13. 

So the surface area would be sum of these areas.

That would be 18×18 + 4( 18 × 40 ) + 4( (1/2) 18×13 ) = <span>3672

Final answer: 3672 m</span>²

Hope this helps.
