Answer:
Length is 22.5 ft
Width is 16.5 ft
Step-by-step explanation:
4L-w=73.5
4L=73.5+w
L=(73.5+w)/4
P=78
P=2L+2w
78=2[(73.5+w)/4]+2w
78=(73.5+w)/2+2w
78=(73.5+w+4w)/2
2•78=73.5+5w
156=73.5+5w
156-73.5=5w
82.5=5w
82.5/5=w
16.5=w
L=(73.5+w)/4
=(73.5+16.5)/4
=90/4
L=22.5
Hello from MrBillDoesMath!
Answer:
(x^4-2) (x^4 -1)
Discussion:
Let u = x^4, then
x^8 - 3x^4 + 2
= u^2 - 3u + 2
= (u -2) ( u -1)
= (x^4-2) (x^4 -1)
Thank you,
MrB
