Prove that each of the expressions below are equivalent by evaluating the expressions given. Given g = 3. 15g-2(2g+6) and 11g-12

Answer with Step-by-step explanation:

We are given that

g=3

and

We have to prove that two expressions are equivalent by evaluating the expressions given

Substitute the value of g in the given expression

Substitute the value of g in the given expression

Hence,

15g-2(2g+6) = 11g-12 when g=3

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
