Add. Express your answer as a polynomial in standard form. 3(x² + x + 9) + 8(x - 3) =

a

b

d

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

x = 1/2

step-by-step explanation:

hope this !

the answer is x=45 because i said so
