Use the zero product property to find the possible solutions to the equation x2 – 9 = 16.

  x = -5 or +5

Step-by-step explanation:

Subtract 16 and factor.

  x^2 -9 = 16 . . . . . given

  x^2 -25 = 0 . . . . subtract 16; the difference of squares

  (x -5)(x +5) = 0 . . . . the factored form

The zero product property says possible solutions are found where the factors are zero.

For (x -5) = 0

  x -5 = 0

  x = 5 . . . . . add 5

For (x +5) = 0

  x +5 = 0

  x = -5 . . . . . subtract 5

Possible solutions are x=-5 or x=5.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
