They are intersecting because if you take the equaton 3x+2

We are going to rearange both of these into slope intercept form.
First: 2y = -3x + 19 -> y = -1.5x + 9.5
Next: -5y = -4x + 10 -> y = .8x - 2
Finally: Because the two slopes are not the same, we know the lines are intersecting.

$(a+b)^2=a^2+2\cdot ab+b^2\\\\293=a^2+2\cdot 14+b^2\\\\293=a^2+28+b^2\\\\a^2+b^2=293-28\\\\\boxed{a^2+b^2=265}$
