1. x(2x^2-x+4)
2.-3(y-1)(y+2)
3.-(11w^2+18w-1)
I believe it is a rational number
I believe its the last one 8v2
We know that
[volume of larger figure]=[scale]³*[volume of smaller figure]
scale=∛(volume of larger figure/volume of smaller figure)
scale=∛(2744/729)-----> 1.56
[surface area of the larger figure]=scale²*[<span>surface area of the smaller figure]
</span>[surface area of the smaller figure]=[surface area of the larger figure]/scale²
[surface area of the smaller figure]=[392]/1.56²----> 162 mm²
the answer is
the surface area of the smaller figure is 162 mm²
