Find the surface area of the regular pyramid.

D

Step-by-step explanation:

It helps to break the pyramid into shapes

triangles:  ((b x h) ÷ 2) x 5

((4 x 8) ÷ 2) x 5= 80in

base: 27.5in

total sa: 27.5 + 80 = 107.5in

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 )
