Answer:-2
Step-by-step explanation:
(n + 3) 5 = 3 x 1 - n
distribute so 5n + 15= 3 - n
subtract three from both sides
5n - 12 = -n
subtract 5n from both sides
12 = −6n
Divide both sides by -6
n=-2

Answer:
Step-by-step explanation:
surface area of cube = 6×8² = 384 cm²
lateral area of pyramid = surface area of pyramid - base area
= 384 - 8²

area of triangular face = 320/4 = 80 = ½(base)(slant height) = ½(8)(slant height)
slant height = 20 cm
