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.

Degger [83]
Answer:
from 7 to 49 or (7, 49)
Step-by-step explanation:
Range means the limit of the data set. Basically, the low part of the range is the lowest number in the set and the high part of range is the highest part.
Answer:
.
Step-by-step explanation:

We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is
we get;

Now we will take the common factor from the last 2 terms which is 3 we get;

Here we get 2 terms in which
is common factor.

Hence After factorizing the given equation we get
.
