Similar polygons only differ by a scaling factor. In other words, two polygons are similar if one is the scaled version of the other.

In particular, this implies that the angles are preserved, and the correspondent sides are in proportion.

These two polygons are both rectangles, so the angles are preserved. We must check the sides, and we have to check if the smaller sides are in the same proportion as the bigger sides.

So, the two rectangles are similar if the following is true.

4\div 5 = 11\div 12

In any proportion, the product of the inner terms must be the same as the product of the outer terms:

4\cdot 12 = 5\cdot 11 \iff 48=55

This is clearly false, and thus the two rectangles are not similar.

ElenaW [278]

Answer:

The second term defines the value that will be depreciated by the rate of 22 units for m months.

Step-by-step explanation:

Given is :

The value of the gadget after 'm' months = 2020 - 22m

This expression tells us that, each month Meghan's gadget's price falls by 22 units from the original value.

The original value of the gadget is 2020 units.

Therefore, the constant term (2020 )of the expression represents the original value of the gadget,

And the second term defines the value that will be depreciated by the rate of 22 units for m months. And m defines the number of months Meghan will keep the gadget.
