Answer:
Sarkis cannot draw a triangle with these side lengths.
Step-by-step explanation:
Sarkis cannot draw a triangle with these side lengths.
Well, first of all, LCM means Lowest Common Multiple. So you have to write out the factors of each of the numbers. So that will be;
2= 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
5=5, 10, 15, 20
So now, you have to pick out the numbers that are common to both numbers. So;
10, 20
10 and 20 are the only common numbers. So you have to look for the lowest common number. And that is 10. So the LCM is 10.. Hope i helped. Have a nice day.
0.4x + 3.9 = 5.78
1. Subtraction property of equality:

0.4x = 1.88
2. division property of equality:
Divide both sides of the equal sign by 0.4:
X = 4.7
