Choose all of the equations that are true.

x2 + 2x − 24 = (x + 6)(x − 4)
x2 − 8x + 15 = (x + 5)(x + 3)
3x2 + 4x + 1 = (3x + 1)(x + 1)
5x2 − 2x − 3 = (5x + 3)(x − 1)
4x2 − 49 = (2x − 7)(2x + 7)

What are the steps to solving the inequality 3b + 8 ≥ 14?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
