5=5ax+1 please help, its due in an hour.<br><br> solve for x
RUDIKE [14]

Answer:

x= 4/5a

Step-by-step explanation:

5=5/ax+1

Step 1: Multiply both sides by a.

5a=a+5x

Step 2: Flip the equation.

a+5x=5a

Step 3: Add -a to both sides.

a+5x+−a=5a+−a

5x=4a

Step 4: Divide both sides by 5.

5x/5=4a/5

x= 4/5a

Hope this helps!

What is the coefficient of x2 in the expansion of (x + 2)3?
wolverine [178]
One way is that you can just factor it out: (x+2)(x+2)(x+2)
For the first pair, you get x^2+4x+4.
Then do (x^2+4x+4)*(x+2)
That will be x^3+6x^2+12x+8
So the answer is 6
