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.
Answer:
y = -6x + 5
Step-by-step explanation:
The first thing you should know about a perpendicular line is that the slope is the opposite reciprocal. So, this is your current equation: y= -6x + b. Plug in your coordinate to the equation to get this: 23 = -6(-3) + b. Multiply -6 by -3 to get 18. This is what is should look like: 23 = 18 + b. Subtract 18 from both sides to get your y-intercept of 5. Go back to your original equation and plug in 5 to b. This is your final equation: y = -6x + 5. Hope this helped!
