It’s 17 i’m pretty sure because 20+ 5 is 25 and 25 - 10 is 15 then 15+5=20 and 20-3 is 17

Answer:

What is the perimeter of a rectangle that is 18 inches wide and 23 inches long?

P = 2(l+w)

l = 23, w = 18

P = 2(23 + 18)

P = 2(41)

P = 82

So the perimeter of the rectangle is 82 inches.

Hope this helped! Have a great rest of your day! :)

Can an answer be incorrect even if it looks reasonable?
Anna [14]

Answer:

  • <em>Yes, an answer can be incorrect even it it looks reasonable.</em>

Explanation:

Yes, an answer can be incorrect even if it looks reasonable, for two main reasons:

  • The assumptions (premises or statements) on which the reasoning is based are wrong.
  • The reasoning sounds good but it is a fallacy.

To avoid the first condition you must be sure about the facts, which may be information from an experiment that you performed or from a source. In order for an answer be correct, make sure your premises are true.

Dealing with the second condition, a fallacy is an argument that seems strictly logical but is misleading: you must learn which reasonings are really valid; this is, that the conclusion unequivocally follows from the premises.

There are rules for the arguments to be valid, and that is the object of logic study.

Fallacies are sometimes used by those interested in supporting a point of view without having true reason on their side. You should have some knowledges about logic to avoid being victim of the fallacies, which can drive you to make wrong decisions.
