Answer:
D
Step-by-step explanation:
Given
x³ + 2x² + 7x + 14 ( factor the first/second and third/fourth terms )
= x²(x + 2) + 7(x + 2) ← factor out (x + 2) from each term
= (x² + 7)(x + 2) → D
Answer:
....

Answer:
the flagpole is 12 ft
Step-by-step explanation:
2.5 ft / 4 ft = 7.5 ft / x ft
2.5x = 30
2.5x/2.5 = 30/2.5
x = 12 ft
Not so sure, but I think x is equal to 3/7. So from there you can calculate the answer I guess... This isn't elementary math lol... it's more of middle school math.
