I think answer should be d. Please give me brainlest let me know if it’s correct or not okay thanks bye
Are these simultaneous questions or like seperate ones?
Simultaneous:
4x -3(7x-4) = 12
4x - 21x + 12 = 12
-17x = 0
X = 0
Therefore y = -4
***
If it's a graph
x int: (3,0)
Y int: (0, -4)
Um idk if that's the answers you wanted but I hope it helped somehow??
Answer: ill try it -3-
Step-by-step explanation:
Answer: D) (x+1)(x + 2)(x-3)
This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side
x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0
The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)
