Answer:
4x - 4y - 7z
Step-by-step explanation:
x - 3y + 4z + y - 2x - 8z + 5x - 2y - 3z =
(x - 2x + 5x) + (y - 3y - 2y) + (4z - 8z - 3z) =
4x + (- 4y) + (-7z) =
4x - 4y - 7z <===
This equation can be written as
(v-8)(v+5)/ (v-8)(v-3)
= v+5/v-3
Answer:
63°
Step-by-step explanation:
Vertical angles are equal to each other.
The sum of the two smallest numbers has to equal a number greater that the largest one. Or, how some people prefer it, the sum of any two numbers of the set has to be a greater number than the third one.
So, the set of sides 7,9,17 does not form a triangle.
because 7+9= 16, which is less than the greatest number, 17.
