25,000 - 8,500 = 16,500
16,500 :1250 = 13 years and 2 months
H/4=7/14
we cross multiply , so
14*h = 7*4
14h=28
divide by 14 on both sides
h=28/2=2
The difference in distance between Aero plane A and B is; 34.67 km
<h3>How to calculate bearing?</h3>
To get the bearing;
∠H = (115 - 90) + (270 - 203)
∠H = 92°
Then, we will use cosine rule to get the distance between both Planes A and B.
d_ab = √(18² + 29² - 2(18 * 29) * cos 92)
d_ab = √(324 + 841 + 36.435)
d_ab = 34.67 km

The greatest common factor (GCF) is the product of the greatest common factors of the numerical coefficients and the variables involving x and y.
-12(x^4)y - 9x³y² + 3x²y³
-3x²y(4x² + 3xy - y²)
<span>Thus, the answer is letter A. </span>
