I have no idea what in the world all those 9s are doing there,
but the decimal form of 69/25 is 2.76 .
3/4 x 21
=
3/4 x 21/1
=
63/4
Complete the SquareSolve for x over the real numbers:(x - 8)^2 - 100 = 0
Add 100 to both sides:(x - 8)^2 = 100
Take the square root of both sides:x - 8 = 10 or x - 8 = -10
Add 8 to both sides:x = 18 or x - 8 = -10
Add 8 to both sides:Answer: x = 18 or x = -2
Shouldnt you divide? This s a guess. I never learned this but i think it goes by dividing.
