Answer:52 ft.
Step-by-step explanation: If the area of the base of the pyramid is
169
ft
2
then each side of the base is
13
long because the base of the pyramid is a square.
Length of the side,
s
=
√
Iif we take the area of a square
A
where
we get the area of the base to be
thus proving that each side of the base is
long.
So to find the perimeter of the base of the pyramid we use the formula:
P
4
and thus,
p
⋅
52
Answer:
^(3)+7x^(2)+4x-12
Step-by-step explanation:
Answer:x= 5/2 x= -1/2
4(x-1)2-9
4(x2-2x+1) - 9
4x2 - 8x + 4 - 9
4x2 - 8x - 5
4x2 +2x - 10x - 5
2x(2x+1) - 5(2x+1)
(2x-5)(2x+1)
therefore, x= 5/2 x= -1/2

48 + 14 / 2 = 31
0= 0/8
1/2= 4/8
1= 8/8
5/8 is closer to 1/2.
