Okay luv so let's solve this equation together:
8n-(2n-3)=12
simplify
8n+-1(2n-3)=12
8n+-1(2n)+(-1)(-3)=12
8n+-2n+3=12
(8n+-2n)+(3)=12 Combine like terms
6n+3=12
Then subtract from both sides
6n+3-3=12-3
6n=9
Then divide both sides by 6
6n/6=9/6
so...n=3/2
Answer:
Step-by-step explanation:
the first one is correct
Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
= 8²
= 64 cm²
Area of one lateral triangle = 
= 
= 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
= 64 + 128
= 192 cm²
Therefore, Option (D) will be the correct option.
