Answer:
x=-2
Step-by-step explanation:
add 18 to both sides, simplify, add 6x to both sides, simplify, divide both sides by -12.then simplify again... I hope that helps...
The minimum sum is 3 and the maximum is 11. So there are 9 different possible sums.
There are 30 ways to get these 9 different sums.
The table below shows all outcomes.
1 2 3 4 5 6
———————————-
1 | X 3 4 5 6 7
2 | 3 X 5 6 7 8
3 | 4 5 X 7 8 9
4 | 5 6 7 X 9 10
5 | 6 7 8 9 X 11
6 | 7 8 9 10 11 X
Since you've told us that this is an isosceles triangle, we know that the 'legs' have equal length. So we can write
x + 1 = -x + 7
Add 'x' to each side: 2x + 1 = 7
Subtract 1 from each side: 2x = 6
Divide each side by 2 : x = 3
Now, if the length of the base is 3x - 3 ,
that length is
3(3) - 3 = 6 .
