Which expression is equivalent to 10a - 25 + 5b
choose 3 answers.

A. (2a−5+b)5
B. −2(−5a−25+5b)
C. 10×(a−2.5+0.5b)
D. (−2a+5−b)⋅(−5)
E. −10⋅(−a−2.5−0.5b)

answer A

Step-by-step explanation:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

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
