Answer:

x= 6

Step-by-step explanation:

12+3x=30

3x+12=30

3x+12-12=30-12

3x=30-12

3x=18

3x divided by 3 = 18 divided by 3

x=18 over 3

18 divided by 3 is 6

x=6

Answer:

x = 6

Step-by-step explanation:

12 +3x = 30

Subtract 12 from both sides

3x = 30 - 12

3x = 18

Divide both side by 3

x = 18/3

x = 6

Please help me <br>find f(x+h)

Kay [80]

Answer:

f(x) = -2x+5

f(x+h) = -2x -2h +5

g(x) = -4x-2

g(x+h) = -4x -4h -2

h(x) = 4x^2+1

h(x+h) = 4(x+h)^2 +1 = 4x^2 +8xh + 4h^2 +1

Q(x) = -3x^2 +4

Q(x+h) = -3(x+h)^2 +4 = -3x^2 -3h^2 -6xh + 4
