-3|x + 7| = -12
|x + 7| = -12/-3 = 4
x + 7 = 4 and x + 7 = -4
x = 4 - 7 and x = -4 - 7
x = -3 and x = -11

If human height were quantized in one-foot increments, what would happen to the height of a child as she grows up?

agasfer [191]

I believe what the problem means is that the height of the child, if he/she grows in height, the mesurements are equal to 1 ft, 2 ft, 3 ft, 4 ft, etc only. and no decimals or fractions in between. it is also said that a human stops growing at the age of 20 naturally, hence with this increment, a child can grow incredibly very tall.
