Answer:
x^4-9x^3+39x^2-225x+350
Step-by-step explanation:
The simplest polynomial you can get with that roots are (x-5i)(x+5i)(x-2)(x-7)=x^4-9x^3+39x^2-225x+350
D. is a difference of perfect squares because both terms 25x^2 and 36 is a square (5, x, and 6). Also, difference of perfect squares MUST have a minus sign.
Answer:
800 km
Step-by-step explanation:
Does the plane have a speed of it's own? I don't see it, so will assume the plane is simply travelling at 300 km/h.

(5 km/min)*(160 min) = 800 km in 160 minutes
X (greater than or equal to “>”) 985
