Answer:
7
Step-by-step explanation:
Using fundamental theorem of algebra, there should be 7 roots, if you count multiplicity.
If you're only counting distinct roots, then there should be 4 roots.
1. x
2. x + 2
3. x + 4
x + 4 + 2x = 25. Second option is the answer.
Combine like terms
3x + 4 = 25
Subtract 4 from both sides
3x = 21
Divide both sides by 3
x = 7
Replace x with 18, solve the equation. If it equals -4 it’s a solution.
Y = -6(18) - -87
Y = -108 + 87
Y = -21
-21 does not equal -4 so (18,-4) is not a solution.
