Solve 2x - 8 + 3x &gt; 5x - 4 also if you can plz explain
WITCHER [35]

Answer:

No solution

Step-by-step explanation:

2x - 8 + 3x > 5x - 4

2x + 3x - 8 > 5x - 4

5x - 8 > 5x - 4

-5x +8 > -5x  +8

----------------------

0x > 4

This is no solution, as there is no 'x' value.

(0x just means there isn't anything left, I put that in order to show there wasn't anything.)

Would you say that pythagoras’ theorem holds true for hexagons as well? why or why not
kifflom [539]
No, the Pythgorean Theorem only applies to right triangles. To get two right triangles, you divide a rectangle diagonally. Dividing a hexagon into two pieces produces trapezoids or pentagons depending where it is divided.

Need help fast please!!!!
Travka [436]
A. m < 125° is the answer 

when added together the two angles must be less than 180 degrees. 

when you subtract 55° from 180° you get 125° so you know the angle must be less than 125° since 125° + 55° = 180°
