would it combine to 4x-6? @Photon336

photon336 · Answer

sorry i made a mistake earlier 

(8x-4)-(4x-6) = 4x+2 

(4x+2)+(4x-6) = 8x-4

the value of the other side should be 2x+1

(4x+2)*(1/2) = 2x+1

photon336 · Answer

because (4x-6) + (4x+2) = 4x+4x = 8x  -6+2 = -4   so 8x-4 

so the value of the side you're looking for should be 2x+1

photon336 · Answer

the perimeter is the sum of all the sides, so the sum is 8x-4 so you need to subtract 2x-6 from that to find the value of the other two sides.

@frebrezze does this make sense?
