So distribute
2x+2+8=6
add like terms
2x+10=6
-10 -10
2x=-4
---------
2. 2
x=-2
Since a kilogram is 1000 grams, 4*1000=4000 kilograms, which is your answer
Scale factor is given by:
(length of larger figure)/(length of smaller figure)=(width of larger figure)/(width of the smaller figure)=3.4
The length of the larger figure will be given by:
length=(scale factor)*(length of smaller figure)
=3.4*6=20.4 cm
width of the larger figure will be given by:
width=(scale factor)*(width of smaller figure)
=3.4*4.5
=15.3 cm
Therefore the dimension of the new parallelogram will be 20.4 cm by 15.3 cm
X + 19 >= 8.2
x >= 8.2 -19
>= -10.8
