Given:
Side length of base = 8
Slant height = 6
To find:
The surface area of the square pyramid.
Solution:
Surface area:

where A is the area of base
p is the perimeter of base
s is the slant height
Area of base (A) = 8 × 8
= 64
Perimeter of base(P) = 4 × 8
= 32
Substitute these in the formula:



The surface area of the square pyramid is 160 unit².
Answer: the vertex is (12,−144)

Answer:
-7
Step-by-step explanation:
-3 - (4) = ?
Remove parentheses:
= -3 - 4
Subtract the numbers:
= -7
Hey, here it is: 2,4 x 10^-6
no solutions → C
The 2 given lines are parallel and never intersect thus no solution
