Answer:

30y - 18x +12

Step-by-step explanation:

Distribute (multiply) -6 to all terms within the parenthesis. Remember to follow the sign rules: negative x negative = positive ;  negative x positive = negative

-6(-5y) = 30y

-6(3x) = -18x

-6(-2) = 12

Combine:

30y - 18x + 12 is your answer

Becky's ship is 43 miles west all the harbor.
pishuonlain [190]

Answer:

Clyde is 49.74 away from the harbor

Step-by-step explanation:

Here in this question, we are interested in knowing the distance of Clyde from the harbor.

The key to answering this question is having a correct diagrammatic representation. Please check attachment for this.

We can see we have the formation of a right angled triangle with the distance between Clyde’s ship and the harbor the hypotenuse.

To calculate the distance between the two, we shall employ the use of Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides.

Let’s call the distance we want to calculate h.

Mathematically;

h^2 = 25^2 + 43^2

h^2 = 625 + 1849

h^2 = 2474

h = √2474

h = 49.74 miles
