Answer:
x = 32.6666667
Step-by-step explanation:
12(x - 2) + 3x = 12(x + 6) + 2
Distribute;
12x - 24 + 3x = 12x + 72 + 2
Collect like terms;
15x - 24 = 12x + 74
Subtract 12x from both sides;
3x - 24 = 74
Add 24 to both sides;
3x = 98
Divide both sides by 3;
x = 32.6666667
Answer:
1/2(6)(2 + x) = 27
3(2 + x) = 27
6 + 3x = 27
6 - 6 + 3x = 27 - 6
3x = 21
3x / 3 = 21 / 3
x = 7

Answer:
The answer is B, Perpendicular
Step-by-step explanation:
KM
K= (-3, -7)
M= (3,-3)
The equation is
So (-3)-(-7) =4
And (3)-(-3)=6
-4/6= 2/3
ST
S= (0,4)
T= (6,-5)
So it would be
(-5)-(4)=-9
(6)-(0)= 6
-9/6=
-3/2
2/3 in parrallel is 2/3
2/3 in perpendicular is -3/2
