Ask your parents about it if they didn't help you can copy mine,
Well I asked my parents about they told me that around their age there weren't lots of facilities they even rarely saw transportation facilities like cars and bikes there were no proper internet facilities e.t.c
When I said them what were the changes in the last 25 years they said there were drastic changes including social, economic, science, transportation, health e.t.c and many more
The missing factor is (a -1) I believe. If you foil (5a + 9)(a - 1) you would get 5a^2 + 4a - 9.
L being the length, W being the width.
So:
if the Length is 8cm more than twice the width, we have:
2W+8
so it's:
perimeter of a rectange = 2(2W+8)+2W
You asked me not to simplify it, so that should be your answer.
Answer:
Formulate
Based on the given conditions, formulate:
Evaluate
Evaluate the equation/expression:
20.78461
SO THE ANSWER IS 20.78461
18.10 = 18.1
6,324.50 = 6,324.5
