x³ + 2x² - 9x - 18 = 0
x²(x+2) - 9(x+2) = 0
(x + 2)(x² - 9) = 0
(x + 2)(x - 3)(x + 3) = 0
the answer is d.
Answer:
2
Step-by-step explanation:
3 * n = 6
/3 /3
n = 2
Answer:
(4, 3)
Step-by-step explanation:
Since the x is by itself in the first equation already, we can solve for y in the next equation and substitute for x.
(y+1)+2y=10
3y+1=10
<u>-1 -1</u>
3y=9
y=3
Next, we need to find x. To do this, we need to substitute y with 3 in one of the equations.
x=(3)+1
x=4
The ordered pair is finally (4, 3).
Hope this helps!! I literally just learned this today...have a great day ❤
