Answer:
B)3x=15
Step-by-step explanation:
3x=15
x=15/3
x=5 (proven)
Answer:
2
Step-by-step explanation:
consider the two points. Gradient=change in y/change in x. So 4/2=2
The rational root theorem states that the rational roots of a polynomial can only be in the form p/q, where p divides the constant term, and q divides the leading term.
In your case, both the leading term 5 and the constant term 11 are primes, so their only divisors are 1 and themselves.
So, the only feasible solutions are

For the record, in this case, none of the feasible solutions are actually a root of the polynomial.
They need to be number C plus 3-2:7
