Answer:
z=20
Step-by-step explanation:
(2z + 16) +124 =180
2z + 16 +124
2z + 140 = 180
2z -140 -140
2z = 40
z = 20
Answer:
251.2 units³ ; 80π units³
Step-by-step explanation:
Volume of a Cylinder is: 
'r' is the radius.
'h' is he height.
The cylinder has a base radius of 4 units and the height 5 units.
<h3>Using 3.14 for Pi:</h3>

The approximate volume is 251.2 units³.
<h3>In terms of pi:</h3>

The exact volume is 80π units³.
Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
