Answer:
area=56000 yards²
Step-by-step explanation:
first divide 280 by 7 and get 40
scale factor is 40
5x40=200
200x280=56000
area=56000 yards²
Answer: 7
Step-by-step explanation:
Polynomial with real coefficients always has even number of complex roots. We know that one of them is 2 + 5i so the second one will be 2 - 5i and:

Answer B.
(a + 1)(a² + 2a + 1)
= a(a² + 2a + 1) + 1(a² + 2a + 1)
= a³ + 2a² + a + a² + 2a + 1
= a³ + 3a² + 3a + 1
