I'd explain, but I think you got it.
Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !

Answer:
<u>18°</u>
Step-by-step explanation:
sin 2x=cos zy
m(2x)=72°
cos(π/2-a)=sin a
cos(π/2-72°)=sin72°
cos18°=sin72°
=>m(zy)=18°
Answer:
-169
Step-by-step explanation:
We want to isolate v.
Method 1: subtract 40 from both sides, obtaining 169 = -v. Then change the sign of both sides, arriving at v = -169.
Method 2: Add v to both sides. Then v + 209 = 40.
Now subtract 209 from both sides, obtaining -169.
