Answer:
Step-by-step explanation:
We observe that the second equation of System B has had the x-term eliminated. That can be accomplished by adding 3 times the first equation to the second.
"To get System B, the <u> second </u> equation in System A was replaced by the sum of that equation and <u> 3 </u> times the <u> first </u> equation. The solution <u> is </u> the same as the solution to System A."
Answer:
The length of the third side could be 9 ft
Step-by-step explanation:
we know that
<u>The Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
In this problem
Let
c-----> the length of the third side, in feet
Applying the Triangle Inequality Theorem
1)
------->
2)
----->
so
The length of the third side must be greater than 4 ft and less than 16 ft
Remember that
The scalene triangle has three different sides
therefore
The length of the third side could be 9 ft
I am pretty sure the answer to your question would be $160
