Step-by-step explanation:
(6x^3 + 4x-2) + (4x^2 + 3x^3 - 6)=
6x^3 + 4x-2 + 4x^2 + 3x^3 - 6=
9x^3+4x^2+4x-8
D
where they meet at is 2,6
Answer:
176 sq ft
Step-by-step explanation:
The height of each lateral face is the slant height of the pyramid.
LA = 1/2(PL) where P is the perimeter of the base and L is the slant height.
SA = surface area B = area of base LA = lateral area
SA = B + LA = B + 1/2(PL)
P = 4(8) = 32 B = (8)(8) = 64 L = 7
SA = 64 + 1/2(32)7
SA = 8(8) + 1/2(32)(7)
= 64 + 112
= 176 sq ft.
