Answer:
D.) 4m, 11m, 9m
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side in order to form a triangle. Using the two shortest sides, you can find the sum and check to make sure it is larger than the third:
3m + 3m = 6m NOT greater than 6m
4m + 7m = 11m NOT greater than 12m
5m + 3m = 8m NOT greater than 9m
4m + 9m = 12m YES greater than 11m
30b^2-50 is your answer, so D and you should know this if you have rated yourself as college leveled.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)
