Answer:
144
Step-by-step explanation:
1) expand the brackets
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
simplify
-18 - 8x = 14
then add 18 to both sides to get the x's on there own
-8x = 32
then divide by -8
x = 32/-8
x = -4
2) multiply everything by 7x
2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x
2 + 42x + 119x^2 = 126x
put everything on one side
119x^2 - 84x + 2 = 0
then use quadratic equation to solve
x = 0.024671849 or 0.6812105039
Answer:
a
Step-by-step explanation:
you divide three from both sides and get m-3 = -2. then you add 3 to both sides and get m=1
39.
|z+7|=12/3
|z+7|=4
z+7=4
-(z+7)=4
solve the first equation:
z+7=4
z=-3
solve the second equation:
-(z+7)=4
z=-11
z=-11,-3
