Answer:
The first one.
Step-by-step explanation:
The polynomial is made out of three terms so we would consider it a ”trinomial” and since it is a second degree polynomial (based on the highest degree) it would be “quadratic.”
Substitute the value in for x and evaluate.
x^2+4x+4
Answer:
27. C
28. D
Step-by-step explanation:
The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.
