Easy
differnce of 2 perfect squares
a²-b²=(a+b)(a-b)
in this case
x⁴=(x²)²
16=4²
(x²)²-4²=(x²+4)(x²-4)
x²-4 can be factored since 4=2²
x²-2²=(x+2)(x-2)
complete factored form is
(x²+4)(x+2)(x-2)
gegroup to seperate (x+2)
(x+2)[(x²+4)(x-2)]
(x+2)p(x)
p(x)=(x²+4)(x-2)
expanded
p(x)=x³-2x²+4x-8

The answer is w<6
Step-by-step explanation:
Answer:
A≈150.8yd²
d Diameter 6yd
h Height 5yd
Solution
A=2πd
2h+2π(d
2)2=2·π·6
2·5+2·π·(6
2)2≈150.79645yd²
