Answer:
Z=18.5
Step-by-step explanation:
2(4z - 6 - 6) = 170 - 46
2(4z - 12) = 124 Use distributive property: a(b - c) = ab - ac
8z - 24 = 124 Add 24 to both sides
8z = 148 Divide both sides by 8
Answer: 18.84
Explanation: When looking for the circumference you have to follow a certain formula; C= πd
Since the line is in the middle of the circle, you take half of 12, which is 6, and multiply it by pi. So C= 3.14 x 6 which gives you 18.84

Answer:
(x+1)(x-3i) (x+3i)
Step-by-step explanation:
x^3 + x^2 + 9x+9
We will use factor by grouping
Factor out x^2 from the first group and 9 from the second group
x^3 + x^2 + 9x+9
x^2( x+1) + 9(x+1)
Factor out (x+1)
(x+1) ((x^2+9)
Now factor x^2+9
x^2 -(3i)^2 = (x-3i) (x+3i)
Replacing this
(x+1)(x-3i) (x+3i)
