Answer:
5x+2=0
Step-by-step explanation:
When factoring you add or subtract your factors that are similar.
For example 9x-4x+ 5x
and this is how you get 5x+2=0

R = sqrt 3 * (V /( pi * h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 * (62.8 / (3.14 * 15)
R = sqrt 3 * (62.6 / 47.1)
R = sqrt 3 * 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===
<span>To find the answer we need to find the raduis
Circumference = 2πr
r=</span>

r=

= 104.08
The diameter is 2r, hence the diameter is 208.16
If the rate to cross is 6ft. per second, time can be found by dividing the raduis by 6
It would take 34.7 seconds
The ground, the building, and the ladder form a right triangle, in which
the leaning ladder is the hypotenuse.
For the angle between the ladder and the ground, the 4-ft along the ground
is the side adjacent to the angle, and the 7-ft ladder is the hypotenuse.
(adjacent side) / (hypotenuse) = cosine of the angle.
Cosine(a) = 4/7 = 0.57143... (rounded)
Angle 'a' = <em>55.15 degrees</em> (rounded)
