Is it possible it’s (-2,2)
The definition of a rhombus is that it's a polygon with four congruent sides. If you split one into two pieces with a diagonal, then yes, it will be two isosceles triangles because two sides are congruent.
F(-1) = 2(-1)^2 + 8(-1)
= 2(1) + (-8)
= -6
Step-by-step explanation:
{9x+3y=-36
y=-3x-21
9x-9x-36=-36
y=-3x-21
x=0
y=-21
You will need 82 1/4 1/2 tiles and 165 1/4 tiles
