Isolate the variable by dividing each side by factors that don't contain the variable.

n = 22

Answer:

n=22

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8(5+4n)+11=−5(3−7n)

(8)(5)+(8)(4n)+11=(−5)(3)+(−5)(−7n)(Distribute)

40+32n+11=−15+35n

(32n)+(40+11)=35n−15(Combine Like Terms)

32n+51=35n−15

32n+51=35n−15

Step 2: Subtract 35n from both sides.

32n+51−35n=35n−15−35n

−3n+51=−15

Step 3: Subtract 51 from both sides.

−3n+51−51=−15−51

−3n=−66

Step 4: Divide both sides by -3.

−3n /−3  =  −66 /−3

n=22

Determine algebraically the zeros of f(x)=3x^3+21x^2+36x
Mashcka [7]

Answer:

The zeros of the given polynomial function f(x) are -3,0,-4

Step-by-step explanation:

Given polynomial is f(x)=3x^3+21x^2+36x

To find the zeros of the given polynomial:

First equate the polynomial function f(x) to zero

That is f(x)=3x^3+21x^2+36x=0

By synthetic division we can solve it

-3_| 3      21       36     0

      0       -9      -36    0

   _____________________

      3      12        0        0

      Therefore x+3 is a factor

    That is x=-3 is a zero

    3x^2+12x=0

    3x(x+4)=0

    3x=0 or x+4=0

    Therefore x=0 or x=-4

    Therefore the zeros are -3,0,-4
