3.) Subtract the numbers
4.) Simplify the equation using cross-multiplication
5.) To get the variable on the left side, switch the sides of the equation
6.) Divide both sides of the equation by 60
7.) Reduce the fraction with 5
8.) If any solution equals to the restricted value, exclude it 
   Your answer will be n=1over

Can someone explain this pls
Ludmilka [50]

Answer:

Step-by-step explanation:

( g ° f )(x) = ( x + 7 )² = x² + 14x + 49

20 + 3(x² + 14x + 49) = - 34

20 + 3x² + 42x + 147 = - 34

3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0

D = 196 - 268 = - 72 < 0

There is no any roots in set of real numbers.

The values of x in set of complex numbers are:

x_{12} = \frac{- 14 }{2} ± \frac{6\sqrt{2}i }{2}

x_{12}  = - 7 ± 3√2 i

What is the answers??
yaroslaw [1]
8/3 = 2 x/3 

8/3 = (3*2 +x)/3

a. 8/3 = (3*2+x)/3 

8/3 = (3*2+2)/3

so x = 2 bc. 8/3 = 2 2/3 

b.  
      3 1/6 = (3*6+1)/6

     3 1/6 = (18 +1)/6

     3 1/6 = 19/6

c.  1 - x= 3/8 

    1 -3/8 = x 

x = (8-3)/8

x = 5/8

hope helped
