Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is 
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
C - Associative then Distributive
Associative allows the combining of like terms (Both with variable z)
Distributive allows the 5 to distribute through
5(11z+6z+29)
5(17z+29)
5(17z)+5(29)
85z+145
Step-by-step explanation:
first we need to round 1.37 which you get 1.35 then round 0.9 to 1.0 then add them both which you get 2.35
