Yes
factor out the 2z^2 in each term
(2z^2)(z^2-5z+4)
factor some more
z^2-5z+4
find what 2 numbers multiply to get 4 and add to get -5
the numbers are -1 and -4
(z-1)(z-4)

the factored form is
(2z^2)(z-1)(z-4)

8+—3(6+—6a) help please

LenKa [72]

We know that:

$(+)+(-)=(-)$

and:

$(-)*(+)=(-)$

$8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a$ $=(-10)+18a$

if you have solve for $a$ then:

$(-10)+18a=0$
$18a=10$
$a= \frac{10}{18}$
$a=\frac{5}{9}$

2 feet x 725 = 1450 feet

The real tower is 725 times taller than the actual model.

Ratio:

725 : 1
