7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
When simplified it is: 1-8x
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
It is 8x + 16
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
The expression simplifies to -8x.
16x + 3
When simplified it is: 1-8x
- 8x + 8x = 0 so question is meaningless.
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
4 + 8x
-8x - 10 - 20 = -8x - 30
8x-7+4 = 8x-3 simplified
It is: 8x^2 +68x +32
It is 8x + 16
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
