Two oak trees were bought and planted side-by-side. The first tree was initially 10
feet tall and grew one foot each week. The
second tree started at 3 feet tall and grew 3
feet every two weeks. The equations that
can model the height, y, in terms of the
number of weeks since the trees were
purchased, x are y = x + 10 and
3
y = -x + 3. After how many weeks will
2
the plants be the same height?
e 2

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

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?
