The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle? A 18 by 5
B. 12 by 7
Oc is by a
0.16 by

D (Presumably)

16 by 3

Step-by-step explanation:

The perimeter of a rectangle is the two lengths added with the two widths. In a formula, this is:

Where l is the length and w is the width.

We are told the length is 13 units longer than the width. In other words:

We also already know that the perimeter is 38 units. So, let's substitute P for 38 and l for (w+13) to solve for w:

Distribute:

Combine like terms:

Subtract 26 from both sides:

Divide both sides by 4:

Thus, the width is 3 units.

Since the length is 13 units longer than the width, the length is 16 units.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

you would need to also lose 1 point for each of the other outcomes for it to be fair.
