Answer:
D.the product is negative
for example
2×-1
=-2
If you simplify this expression you get 2x 2 -7x -2
Answer:
a polyhedron is a three dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.
a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense
polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.
solid geometry is the traditional name for the geometry of three-dimensional Euclidean space. Stereometry deals with the measurements of volumes of various solid figures including pyramids, prisms and other polyhedrons; cylinders; cones; truncated cones; and balls bounded by spheres
a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

Answer:
Only 6
Step-by-step explanation:
We need to factor the equation to find the solution. TO factor we need to find what times what = 36, and what plus what equals -12.
-6 times -6 = 36
and -6 + -6 = -12
So this can be factored into
(x-6)(x-6)=0
We can find the solution by setting each parentheses equal to zero.
x-6 = 0
x = 6
So the only solution is 6
I attached an image that shows an example of factoring.
