Answer:
x = 2
Step-by-step explanation:
2x - 10 + 3x - 15 = 10
5x - 25 = 10
5x = 35
x = 7
7 - 5 = 2

Answer:
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
we have the triangle EDF
where

<u><em>Applying the triangle inequality theorem</em></u>
1)

2)

so
The length of DF is the interval -----> (5,13)
The triangle DEF is a scalene triangle (the three length sides are different)
therefore
<em>The statements that are true are</em>
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
Answer:
n=13 s=-6
Step-by-step explanation:
Hope this helps :)
Sum = <span>ax + by + c + 2ax - 3by + c + by - c
Adding and cancelling the like terms
Sum = 3 </span><span>ax - by + c
</span><span>a. 3ax - by + c</span>
