Pretty sure it's (x-7)^2 - 25.
1 km = 1000 meters and 1 hour = 3600 seconds.
9x1000= 9000
9000/3600= 2.5
Your answer would be 2.5 meters per second.
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
ft
long because the base of the pyramid is a square.
Length of the side,
s
=
√
169
=
13
Iif we take the area of a square
A
=
s
2
where
s
=
13
we get the area of the base to be
169
ft
2
thus proving that each side of the base is
13
ft
long.
So to find the perimeter of the base of the pyramid we use the formula:
P
=
4
s
where
s
=
13
ft
and thus,
p
=
4
⋅
13
ft
=
52
ft
Answer:
50,000 + 3,000 + 200 + 70 + 4
Step-by-step explanation:
Expand. Set all non-zero digits by itself:
53,274 = 50,000 + 3,000 + 200 + 70 + 4
Remember to fill in 0 for all digits. They must keep their value.

Answer:
(22, - 24)
Step-by-step explanation:
Multiply the first equation by -5 to make the y's so you can add the up to zero.
-5(2x + y = 20)
-10x - 5y = -100 Add the second equation thn solve for x
<u> 6x + 5y = 12 </u>
-4x = -88
x = 22
Plug 22 in for x in either equation
2x + y = 20
2 (22) + y = 20
44 + y = 20
y = -24
