Answer: 65
Step-by-step explanation:
All those angles added up have to equal 360 degrees.
The little square on the angle to the left of x means that it's a right angle, or 90 degrees.
360
- 180
= 180 <--- this is the bottom half,
180
- 90 <--- the right angle on the left
= 90
90
-25
= 65 <--- that's x
Can you add a little bit more detail? Am I finding out how much the difference is or something?
1/4 times 16x is 4x
1/4 times 4 is 1
4x minus 9x is -5x
So, 1/4 (16x+4)-9x is -5x+1
-5 times x is -5x
-5 times 1 is -5
So,-5 (x+1) is -5x-5
Therefore they are not equivalent
