Answer:
=5
Step-by-step explanation:
perimeter= 2(L)+2(W)
11 =2(1/2)+2W
11=1+2W
11-1=2W
10=2W
Both sides divided by 2
therefore The width is 5
We know that
scale factor=1/4
so
volume of the smaller pyramid=[scale factor]³*volume original pyramid
volume original pyramid=192 unit³
volume of the smaller pyramid=[1/4]³*192---> (1/64)*192----> 3 units ³
the answer is
3 units³
I might be misreading something here but if:
x^5+243=0 subtract 243 from both sides
x^5=-243 raise both sides to the 1/5 power (or take the fifth root of both sides)
x=-3
So there is only one solution, x=-3
