6x^2+14x+4
First factor out all numerical factors (=2 in this case)
2(3x^2+7x+2)
look for m,n such that m*n=3*2, m+n=7 => m=6, n=1
2(3x^2+6x  + 1x+2)
Factor 3x^2+6x into 3x(x+2)
2( 3x(x+2)+1(x+2) )
factor out common factor (x+2)
2(x+2)(3x+1)
=>
6x^2+14x+4=2(x+2)(3x+1)

Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal
cricket20 [7]

Answer:

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

C=\frac{1}{2}\pi D

where

D is the diameter of the semicircle

we have

D=10\ units

substitute

C=\frac{1}{2}\pi (10)

C=5 \pi\ units ----> exact value

Assume

\pi =3.14

C=5(3.14)=15.7\ units ----> approximate value

therefore

The arc length of the semicircle is 5 \pi\ units or 15.7\ units
