writing each one in prime factors:_
1
2
3
2 * 2
5
2 * 3
7
2* 2 * 2
3 * 3
2 * 5
so the smallest number ( the L.C.M) = 1*2*2*2*3*3*5*7 = 2520
The answer is 2520.
Answer:
C. 9×3 + 3×2
The area of the figure is 33 in.
An= A1 r ^(n-1)
An= -4 (-3)^(n-1)
An= -4 (-3)^(7-1)
An= -4 (729)
An= -2916
I think this is right :)
The answer would be 56.10
