2W = P - 2L Explain why the expression P - 2L cannot be simplified further.

They are not like terms, so the following expression cannot be simplified.

Step-by-step explanation:

Given the following question:

P - 2L

The following expression cannot be simplified further because it "does not share like terms." Like terms is when they have similar variables (example: 2a + 5a) in this case, they do not. Which means you cannot combine like terms by subtracting the two. The reason why the following terms cannot be combined because they have two different variables P, and L are two different variables so they cannot be combined.

Hope this helps.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

i believe it's a.

i'm not sure on this one, most likely correct.
