Answer:
12
Step-by-step explanation:
distribute equation
-2 times k = -2k
-2 times -9 = 18
so -2k+18=-6
solve
subtract 18 from both sides
-2k= -24
divide -2 from both sides
k =12
k=12
-2(k-9)=-6
divide both sides
k-9=3
move the k to the right
k=3+9
add 3+9
the answer is obtuse triangle
40000×1×9%=3 600 this is for year
least to greatest : -54 , -3/9 , 9/5 , 6.6 , 75,
