Yes a square is a type of quadrilateral ( quadrilateral means 'four sides').
Answer:
Step-by-step explanation:
<u>Plot the points first:</u>
- Triangle GHJ: G(1,−6), H(2,−5), J(2,1)
- Triangle NOP: N(−6,1), O(−5,2)
Missing Point P is in quadrant 3and its coordinates are (-6, -5) as per symmetry with triangle GHJ.
Part A is accomplished by first factoring out the b^2 to get

. Factor that completely using the quadratic formula to get

. Part B is done entirely with the quadratic formula (only cuz that's the easiest way to factor a second degree polynomial!) to get (x-9)(x-9) or (x-9) multiplicity 2. Part C is done by taking roots. Keep in mind that since this is a second degree polynomial you will have 2 solutions.

, therefore,

and

which is +11 and -11. And you're done! Factoring is very important...make sure you learn it and learn it well!!!
