What is the factorization of the polynomial below? 3x^2+36x+81
a. (x+2)(x+37)
b. (3x+3)(x+9)
c. 3(x+3)(x+9)
d. (x+3)(3x+9)

C. 3 ( x + 3 )( x + 9 )

Step-by-step explanation:

3x^2+36x+81

3(x^2 + 12x + 27)

3 (x + 3) ( x + 9)

C. 3(x+3)(x+9)

Step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
