How do you solve (2x + 8 )2 =64
Drupady [299]

Answer:

x = 12

Step-by-step explanation:

  1. Write in a different way: 2(2x + 8) = 64
  2. Apply the distributed property, so it now looks like this: 4x + 16 = 64
  3. Subtract 16 from each side, so it now looks like this: 4x = 48
  4. Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12

I hope this helps!
