Answer:
x=5
Step-by-step explanation:
1) Group like terms which will then make the equation 4x-2(x-5)=5x-5
2) Expand the equation (multiply) which will make it 4x-2x+10=5x-5
3) Add similar elements; 2x+10=5x-5
4) Subtract 10 from both sides; 2x=5x-15
5) Subtract 5x from both sides; -3x=-15
6) Divide by 3; x=5
It is 50! Hope this helps.
Answer:
1 solution. Solution is -3.
Step-by-step explanation:
First subtract 8 from both sides. This gives you 5x=2x-9.
Then subtract 2x from both sides. This gives you 3x= -9
Next divide both sides by 3. This would give you that x = -3.

Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2
