For rectangle PLNE, MZPLE = 5x + 2 and m2NLE = 3x. Determine the

value of x, mZPLE, and mZNLE.

i do not know the answer i am sorry

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
