Answers:
1. 74856 + 1489
= 76345
2. 42000/5
= 8400
3. 142100/10
= 14210
4. 2500 + (8-5)
2500 + 3
= 2503
5. 385 + (29 - 9)
385 + 20
= 405
6. 1780 - 643
= 1137
7. 4 x 2 + 30 / 5
4 x 2 + 6
8 + 6
= 14
8. 65743 - 754
= 64989
Answer:
2 + m- 1 + m
Step-by-step explanation:
3m +1 -m
Combine like terms
3m-m +1
2m +1
We can split the m's
m+m +1
And we can rewrite 1 as 2-1
m+m+2-1
m+2+m-1
Rearranging the order
Step-by-step explanation:
0x<3
x>3/0
x>∞
x is undefined.
For get the length of apothem write sin60 = a/4 so sqrt3 /2 = a/4 so a = 4sqrt3 /2
a = 2sqrt3
so area of base = 6(4*2sqrt3)/2 = 6*4sqrt3 = 24sqrt3 unit squared
the lateral area = 4*4*6/2 = 4*2*6 = 48 unit squared
total area = 24sqrt3 +48 = 24(sqrt3 +2) unit squared
hope this will help you
