B is the answer ma brutha
For number 5 you are just multiplying by 4.5
I've seen this question on Brainly before, and I always shake my head.
Please think about this for a few seconds. Maybe even make some
scribbles on a piece of paper.
-- A triangle has 3 sides and 3 angles.
-- A square, rectangle, rhombus or parallelogram has 4 sides and 4 angles.
-- Draw anything with 5 sides. It doesn't have to be pretty, and they don't
all have to be the same length or anything special. Just draw any shape
with 5 sides. Count the angles, and you'll find that there are five of them.
By now you should be starting to get the creepy hunch that maybe a
polygon always has the SAME number of sides and angles. I hope so.
That's the correct creepy hunch.
You can get all kinds of hunches, and even work most of them out,
just by using your thinker for a while.
