X2+12x+35 should be written as x^2+12x+35, where "^"
denotes exponentiation.

Since the coefficient of the x^2 term is 1, we can focus on 35, finding its factors. Note that 35 = 1*35, 5*7. Also note that 5+7 = 12.

Thus, x^2+12x+35 can be re-written as (x+5)(x+7). As a check, multiply 5 and 7; you get 35, which matches the original x^2+12x+35. Then add 5x to 7x, obtaining 12x, which also matches.

Answer:

The distance between the ship at N 25°E and the lighthouse would be 7.26 miles.

Step-by-step explanation:

The question is incomplete. The complete question should be

The bearing of a lighthouse from a ship is N 37° E. The ship sails 2.5 miles further towards the south. The new bearing is N 25°E. What is the distance between the lighthouse and the ship at the new location?

Given the initial bearing of a lighthouse from the ship is N 37° E. So, $\angle ABN$ is 37°. We can see from the diagram that $\angle ABC$ would be $180-37=$ 143°.
