For X=-0.5
3(-0.5)+2
Answer=0.5
For x=-1
3(-1)+2
Answer=-1
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)

Answer:
see explanation
Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ±
( add 1 to both sides )
x = 1 ±
, thus
x = 1 +
or x = 1 - 
Area = 625 cm^2
Area = s^2
Diagonal = s*sqrt(2)
625 = s^2
s = sqrt(625)
s = 25 cm.
Diagonal = s*sqrt(2)
= 25sqrt(2)
=35.36 cm.
=35.4 cm.
