Answer: 384
Step-by-step explanation: 12x8x4=384
(4x - 2)(6(2x + 7)) = 0
(4x - 2)(6(2x) + 6(7)) = 0
(4x - 2)(12x + 42) = 0
48x² + 168x - 24x - 84 = 0
48x² + 144x - 84 = 0
x = <u>-144 +/- √(144² - 4(48)(-84))</u>
2(48)
x = <u>-144 +/- √(20,736 - 16,128)</u>
96
x = <u>-144 +/- √(4,608)
</u> 96<u>
</u>x = <u>-144 +/- 67.88</u><u>
</u> 96
x = -1.5 +/- 0.707083
x = -1.5 + 0.707083 x = -1.5 - 0.707083
x = -0.792917 x = -2.207083

Answer:
-3.1
Step-by-step explanation:
5.1 + 4.2 = 9.3
9.3/-3 = -3.1
Answer:
4 i think
Step-by-step explanation:
(4 – 5) – 6 ≠ 4 – (5– 6) x – y) – z ≠ x – (y – z)
Pretty much you want to find the x and y excess. I don't want to give any answers because I know you are smart. You can do this :)
