Answer:
Option B, z = 2
Step-by-step explanation:
<u>Step 1: Factor</u>
z^2 - 4z + 4 = 0
<em>(z - 2)(z - 2) = 0</em>
<em />
<u>Step 2: Solve for z</u>
z - 2 + 2 = 0 + 2 and z - 2 + 2 = 0 + 2
z = 2 and z = 2
<em>Double root at z = 2</em>

Answer: Option B, z = 2
Answer:
34 hundredhs
Step-by-step explanation:
27 plus 7= 34
<span>2x+14y=-108
</span><span>63x+14y= 14 (multiply the second equation by 7 and subtract)
_____________
-61x=-122
x=-122/-61
x=2
2(2)+14y=-108
4+14y=-108
14y=-112
y=-112/14
y=-8
