(2-sqrt3)/2 = 2/2 - sqrt3/2 = 1 - sqrt(3)/2
Ahhhhhh! 3. Racecar ! (I had to look that one up)
Good one!
Yah....I almost put (hopefully !) after that answer ! LOL
\({5}^{3}\) in this example '3' is an exponent....it is the number of time to multiply '5' by itself 5 x 5 x 5
\({a}^{4}\) 4 is the exponent......this means a x a x a x a
\((x+2)^3 \) '3' is the exponent this means (x+2) x (x+2) x (x+2)
1 Wednesday (whoever she is) paid.
2 YOU are
3 Hmmmm.....
Another problem which MIGHT be clearer to you as a RATIO
495 miles / 9 hours = x / 7hours
SO:
x= 495 miles /9 x 7 (the hours 'cancel') and you are left with = 385 miles
I'm not sure what that is...did you transcribe it correctly?
You're welcome.....keep at it !
- sqrt(2)/2
To find the perimeter you just add all of the side lengths BUT they need to be in the same units.
2.3cm
31mm=3.1cm
.018m = 1.8 cm Now can you do it???
