21=7+7x

-7   -7

14=7x

14÷7=7x÷7  

2=x

x=2

Answer:the two numbers are 2 and 19

Step-by-step explanation:

Let one of the numbers be x

and the second be   7+ 6x

so that the sum of the two numbers which totals 21 be expressed as  

x + (7+ 6x) = 21

x+ 7+6x= 21

7 + 7x = 21

7x= 14

x= 14/7 = 2

one of the numbers = 2

the other number given as

7+ 6x = 7+ 6 x 2= 7+12= 19

The numbers are 2 and 19 .

F(x)=x^3-2x+6 g(x)=2x^3+3x^2-4x+2 Find (f-g)(x).
____ [38]
(f-g)(x) = f(x) - g(x)
  = (x^3 -2x+6) - (2x^3+3x^2-4x+2)
  = x^3 -2x +6 -2x^3 -3x^2 +4x -2 . . . . distribute the negative sign
  = (1-2)x^3 -3x^2 +(-2+4)x +(6-2) . . . . . combine like terms

(f-g)(x) = -x^3 -3x^2 +2x +4
