A. (8,4) because you can tell in the second pattern
(5+22)x(35-27)+6x6
27 (35-27)+6x6
27x8+6x6
27x7+36
216+36
=252
Answer:
B) Isosceles
Step-by-step explanation:
The given triangle has vertices at A(-1,2), B(4,2) and C(3,-1).
We must first determine the length of the sides of the triangle, before we can classify it.
We apply the distance formula to find length of the sides.




.
The length of side BC




The length of side AC

We simplify to obtain;





Since
, the given triangle is an isosceles triangle.
The correct answer is
