2x+3(5-x)-12=4(x+2)
Distribution property:
2x+15-3x-12=4x+8
Add like terms:
-1x+3=4x+8
Add 1x to both sides:
3=5x+8
Subtract 8 from both sides:
-5=5x
Divide by 5 on both sides to get x by itself:
x= -1
Answer:
Step-by-step explanation:
If you're trying to isolate the variable the first thing you would want to do is actually add 9 to both sides.
Answer:
0.8
Step-by-step explanation:
i just did it
That would simplify to 32x^5+400x^4+200x^3+5000x^2+6250x+3125
You would do that because you have to write it repeatedly as (2x+5)(2x+5) and so on.
The answer would be 8+14 because there are 4 sides not 2
