we take cube root separately
![\sqrt[3]{-27} =\sqrt[3]{-3*-3*-3} =-3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-27%7D%20%3D%5Csqrt%5B3%5D%7B-3%2A-3%2A-3%7D%20%3D-3)
We know cuberoot (x^3) is x
![\sqrt[3]{x^9}=\sqrt[3]{x^3*x^3*x^3}=x*x*x= x^3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E9%7D%3D%5Csqrt%5B3%5D%7Bx%5E3%2Ax%5E3%2Ax%5E3%7D%3Dx%2Ax%2Ax%3D%20x%5E3)

#43 is 3 Slices because 12 divided by 4=3
#44 lets work out a bit more. She Practiced 4 hours and 30 minutes each week. There are typically 4 weeks in a month, so we multiply 4 times 4 which is 16. But this isn't our answer because we have the extra half hour. We multiply the half hours times 4, and we have and extra 2 hours on our hands. So this means she Practiced 18 hours each month.
#46 First, You convert everything to inches.
2' 8'=24+8=32 inches.
Divide that 32 in half, and you get 16. 16 inches=16 times 12 =192.
192 over 32 =6.
So in total, 6 boards is your answer :)
Scientist look at various evidence like fossils, rocks, and glaciers to determine what it is like millions of years ago. Evidence like rocks, movement of the tectonic plates and glaciers can determine the landforms and climate of an area. Evidence like fossils, combined with the current knowledge of evolution and the climate at that time allows scientists to hypothesize what it looks like millions of years ago.
Answer:
the equations are coincident.
