I believe the greatest common factor would be 1 because there are no other multiples that are the same. 1•21=21, and1•40=40
This is a geometric progression pattern with the common ratio of negative 0.5.
The next three would be -0.5, followed by 0.25, followed by -0.125
One of the easiest methods that can be used to find the area of a polygon is to split the figure into triangles
Question 4- You need to subtract the shortest bolt from the longest bolt, or 1 1/4 minus 3/8. Make 1 1/4 improper and make the denominator 8 so multiply 5x2=10 and 4x2=8. 10/8 - 3/8 equals 7/8 and thats your final answer. Hope this helped ;)
12.826+2.93= 15.756
Since you have to round it, your final answer would be 15.8
