Solve: 16x2 − 81 = 0.

1 answer:

5 0

Hi there! First we need to add 81 to both sides. 16x2-81+81=0+81=16x2=81. 16x2/16=81/16. Now we get x²=81/16. Now, we have to take the square root. That would be 2.25 or -2.25 it really doesn't matter which answer it is. Therefore, the answer is x=2.25 or x=-2.25.

Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.

Then take 3500 and divide it by 7 which makes 500 thumb tacks.
