Step-by-step explanation:

(4x^3 - 4 + 7x) - ( 2x^3 - x - 8) = 2x^3 + 8x + 4

= (B)

(-3x^2 + x^4 + x) + (2x^4 - 7 + 4x) = 3x^4 - 3x^2 + 5x - 7

= (D)

(x^2 - 2x)(2x + 3) = 2x^3 - x^2 - 6x

= (A)

Solve each equation. 1. 25 - 3x = 40 2. } (x – 10) = -4

nordsb [41]

Step-by-step explanation:

For no 1

25 - 3x = 40 

- 3x = 40 - 25 

- 3x = 15 

 - x = 15 / 3

Therefore x = - 5 

Now for no. 2

1/3 ( x - 10) = - 4 

( x - 10 ) = - 12 

x = - 12 + 10

Therefore x = - 2 

Hope it will help :)

Solve each equation. List any restrictions. Check your solutions. 12/x+11=17

Thepotemich [5.8K]

12+11x=17x11x+12=17x
(both sides of the equation)
11x+12−17x=17x−17x
(Subtract 17x from both sides)
−6x+12=0−6x+12−12=0−12
(Subtract 12 from both sides)
−6x=−12−6x−6=−12−6
(Divide both sides by -6)
x=2
Check answers. (Plug them in to make sure they work.)
