Answer:
the answer is d
Step-by-step explanation:
The really short answer is, there are 5 weeks, and the temperature dropped a total of -15 celsius on those 5 weeks, how many times does 5 go into -15? -15/5 or -3, so each week, evenly it dropped -3 celsius, and after 5 weeks, it added up to -15 celsius total from the first one.
so in the first week, or week 1, it dropped -3(1), on week 2 it dropped -3(2) on week "w" it dropped -3(w), f(w) = -3w.
There are 6 sides to a hexagon and each side of the fence will be 6+2 = 8 feet
So you'll need 8*6 = 48 feet of fencing.
![384=2^7\cdot3=2^6\cdot2\cdot3=(2^2)^3\cdot6=4^3\cdot6\\\\ \sqrt[3]{384}=\\ \sqrt[3]{4^3\cdot6}=\\ \sqrt[3]{4^3}\cdot\sqrt[3]{6}=\\ 4\sqrt[3]6\Rightarrow C](https://tex.z-dn.net/?f=384%3D2%5E7%5Ccdot3%3D2%5E6%5Ccdot2%5Ccdot3%3D%282%5E2%29%5E3%5Ccdot6%3D4%5E3%5Ccdot6%5C%5C%5C%5C%0A%5Csqrt%5B3%5D%7B384%7D%3D%5C%5C%0A%5Csqrt%5B3%5D%7B4%5E3%5Ccdot6%7D%3D%5C%5C%0A%5Csqrt%5B3%5D%7B4%5E3%7D%5Ccdot%5Csqrt%5B3%5D%7B6%7D%3D%5C%5C%0A4%5Csqrt%5B3%5D6%5CRightarrow%20C)
