Answer:
14
Step-by-step explanation:
We solve this by using 2 to open the bracket
(3+4)2 is the same as 2(3+4)
2(3)+2(4)
=6+8
=14
OR
(3+4)2 is the same as 2(3+4)
So we can solve the one inside the bracket first
=2(7)=14
Circumference = r * 2 * pi
Circumference of track 1 is 376.8
It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
109 numbers hope this helps :)
