The lines y = 2x + 1 and y = -5x - 6 intersect at?

2x+1=-5x-6    x=-1   put x into equation  for example  y=2*(-1)   y=-2   
so intersect at (-1,-2)

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
