The answer is D) 12
8x +14=9x+12
8x+12=9x
12=1x
x=12
The answer is
A(m) = 12 + 2m
B(m) = 10 + 3m
m - the number of months
F(m) - growth in a function of months m
Species A is 12 cm tall, so the number 12 is independent on a number of months. But it <span>grows 2 cm per month. This means that in m months it will grow 2 * m. So, its function is: A(m) = 12 + 2m
Similarly, s</span>pecies B is 10 cm tall, so the number 10 is independent on a number of months. But it grows 3 cm per month. This means that in m months it will grow 3 * m. So, its function is: B(m) = 10 + 3m
4m^2-20mn+25n^2, a perfect square trinomial
Rounded to the nearest thousand is 6,000. But rounded to the nearest thousandth, is 6,051.200
