Answer:
= 3 -1.202
Step-by-step explanation:
(1)the GCF for the polynomial 
4x^3 = 2*2* x* x* x
2x^2y = 2*x*x*y
Greatest common factor is 
(2) the GCF for the polynomial 


GCF is 
(3) the GCF for the polynomial


GCF is 
(4) the GCF for the polynomial 


GCF is 
The length of one segment is 15 cm and other segment is 60 cm
Step-by-step explanation:
Let x be the length of one segment and y be the length of other segment
Then according to given statement
x+y=75 Eqn 1
And
one the segments are four times the other
x=4y Eqn 2


Hence,
The length of one segment is 15 cm and other segment is 60 cm
