Answer:
The lcm is 84
Step-by-step explanation:
3: 3,6,9,12,15,18,21,24,27,30,33,36,39,41,44,47.........84
4: 4,8,12,16,20,24,28,32,36,40,44........84
7: 7,14,21,28,35,42.......84
X = 6 1/2
X is equal to 6 1/2 because, if you subtract 3 1/2 from 10 you will be left with 6 1/2.
the slope of the given point is m=−3/4
Given :
Base (b) = 7.7mm
Area (a) = 210.21mm^2
Height (h) = ?
