We need to apply the following identity:
Then, applying this, you know that for 
:
We need to remember that:
and 
Therefore, we need to substitute these values into .
Then, you get:
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.
Answer:
3/4 x 749.99 ( 750 ) = 562 1/2
562 1/2 = 562.5
Nearest cent 562.10 = 563
Assume the numbers are x , y
x+y =-53
x*y =-24
from equation 1 we get y = -53-x
sub in eqn.2
x* (-53 -x ) = -24
then x^2 + 53x -24 =0
and by solving the equation and substitute we get
the two numbers are
0.449 & -53.452
