What method would you choose to solve the equation 2x^2-7=9? explain why you chose this method.

Sample Response:  I would use the square root property of equality. Because there is no x term, I would just add and divide to get x^2 by itself.  Then I would take the square root.

2x^2 - 7 = 9

2x^2 - 7 + 7 = 9 + 7

2x^2 = 16

2x^2/2 = 16/2

x^2 = 8  (square root of 8 would be square root of 4*2 = 2*square root of 2

x = +/- 2*square root of 2

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
