1/2 of 1/3 of 1/4 of 80ft
= 1/2 of 1/3 of (1/4 of 80ft)
= 1/2 of 1/3 of 20ft
= 1/2 of (1/3 of 20ft)
= 1/2 of (20/3) ft
= 20/6 ft
> 18/6 ft
= 3ft
So the order was longer than 3 feet.
The expression, 25a² + 4, can not be factored with rational numbers. the polynomial is not factorable with rational numbers.
God bless!
7 (seven) is the Correct answer for sure I am positive
Hope it helps
