Answer:
x=-3
y=2
Step-by-step explanation:
To solve this problem you can use the elimination method:
- Multiply the second equation by -6:

- Add both equations:

- Substitute the value of x into one of the original equations and solve for y:

Answer:
So the equation in standard form will be
Step-by-step explanation:
We have given equation 
We have to write this expression in standard form
For writing in standard form first we have to do operation on the expression
We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added
So 
So the equation in standard form will be 
Answer:
The prism
Step-by-step explanation:
The surface area of a cube is:

where
L is the length of the side
For the cube in this problem,
L = 6 cm
So the surface area of the cube is

The surface area of a rectangular prism with squared base is:

where
L is the length of the base
h is the height of the prism
For the prism in this problem,
L = 3 cm
h = 12 cm
Therefore,

So, the prism has a greater surface area.
