What is the product?
(-2x-9y2)(-4x-3)
-8x2-Bx-36 xy2 -27y2
-14x2 - 36 xy2 +27y2
8x² +6x+36xy2 + 27y2
14x2+36 xy2 +27y2

8x² +6x+36xy² + 27y²

Step-by-step explanation:

Expand the following:

(-2 x - 9 y^2) (-4 x - 3)

(-9 y^2 - 2 x) (-4 x - 3) = (-9 y^2) (-4 x) + (-9 y^2) (-3) + (-2 x) (-4 x) + (-2 x) (-3):

-9 (-4) y^2 x - 3 (-9) y^2 - 2 (-4) x x - 3 (-2) x

-9 (-4) = 36:

36 y^2 x - 3 (-9) y^2 - 2 (-4) x x - 3 (-2) x

-3 (-9) = 27:

36 y^2 x + 27 y^2 - 2 (-4) x x - 3 (-2) x

-2 x (-4) x = -2 x^2 (-4):

36 y^2 x + 27 y^2 + -2 (-4) x^2 - 3 (-2) x

-2 (-4) = 8:

36 y^2 x + 27 y^2 + 8 x^2 - 3 (-2) x

-3 (-2) = 6:

36 y^2 x + 27 y^2 + 8 x^2 + 6 x

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
