Answer:
Triangular prism.
Step-by-step explanation:
That would be a triangular prism.
The 3 sides are rectangles and the top and bottom are triangles.
Answer
The difference is -5
Because
In the number line
-3 is in the negative side and
2 is in the positive side
So difference means minus
So,
-3-2
=-5
Remember
- - = + (but the answer should have - sign)
- + = - (the greatest number's sign will be taken)
++ = -
+ - = -

Answer:
first group x's with x's and y's with y's
then complete the squra with x's and y's
2x^2-8x+2y^2+10y+2=0
2(x^2-4x)+2(y^2+5y)+2=0
take 1/2 of linear coeficient and square
-4/2=-2, (-2)^2=4
5/2=2.5, 2.5^2=6.25
add that and negative inside
2(x^2-4x+4-4)+2(y^2+5y+6.25-6.25)+2=0
factor perfect squares
2((x-2)^2-4)+2((y+2.5)^2-6.25)+2=0
distribute
2(x-2)^2-8+2(y+2.5)^2-12.5+2=0
2(x-2)^2+2(y+2.5)^2-18.5=0
add 18.5 both sides
2(x-2)^2+2(y+2.5)^2=18.5
divide both sides by 2
(x-2)^2+(y+2.5)^2=9.25
that is a circle center (2,-2.5) with radius √9.25
