Answer:
Option B will be the correct one.
Step-by-step explanation:
The factor of a polynomial, y = f(x) is obtained by making f(c) = 0 and then solving the equation f(c) = 0 for c and then from the obtained value of c we say (x - c) is a factor of the polynomial y = f(x).
Now, on the reverse, the term (x - a) will be a factor of a polynomial, y = f(x), if and only if f(a) = 0.
Therefore, option B will be the correct one. (Answer)

Answer: No, the two samples do not have similar values, so more samples are needed.
No, the samples are not representative of the population.
Answer:
300 girls
Step-by-step explanation:
100% represents the whole school
To calculate this amount divide 99 by 33% to find 1% and multiply by 100
school population = × 100 = 3 × 100 = 300
Oldest = 2x
Middle = x + 5
Youngest = x
2x + x + 5 + x = 57
combine like terms
4x + 5 = 57
subtract 5 from both sides
4x = 52
divide both sides by 4 to isolate x
x = 13
Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13
