Serena is making a model of the egyptian pyramid. the square base has sides that are all 4.6 in. each of the triangular faces has a base or 4.6 and a height of 4 in. how much paper would it take to cover the entire pyramid

56.96 square inches

Step-by-step explanation:

The amount of paper is the surface area. To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,

Area of square is A=s*s=4.6*4.6= 21.16

Area of a triangle is A= 1/2 b*h = 1/2 (4.6)(4) = 9.2.

There are four equal triangles so together there area is 4*9.2 = 36.8.

Add the square to it and you have the surface area of the pyramid.

36.8 + 21.16 = 57.96

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
