Solve the system of linear equations by elimination.
8x – 5y = 11
4x - 3y = 5

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
