the answer to this is x= -1
3x+17=2x-6
-2x -2x * subtract 2x from both sides* *3x-2x is 1x*
1x+17=-6 *now subtract 17 from both sides*
-17 -17
1x=-23
1x. 1x
x=23
Answer: 216, 343, 512, 729, 1000, 1331, 1728, 2197, 2744
Step-by-step explanation: The terms are the cubes of the numbers 1, 2, 3, 4, 5...
First factor out the 2:
x^2 - y^2 = 36
x^2 - y^2 can be factored into (x+y)(y-y) so:
(x + y)(x - y) = 36
plug in your value:
18 (x-y) = 36 and you should be able to take it from there
