Answer:

Step-by-step explanation:
The formula of a surface area of a rectagular prism:

l - length
w - width
h - height
We have the dimensions 6cm × 14cm × 5cm. Substitute:

Answer:
y = -1/2x + 2.5
Step-by-step explanation:
- slope of a perpendicular line is the negative reciprocal of the original slope (2 in this case) so y = -1/2 x + c
- to find c we substitute the values from the given point into the equation
(0) = -1/2*(5) + c
- rearrange and calculate and you'll get c = 5/2 or 2.5
- replace the value of c and now you've got y = -1/2x + 2.5
