Boston is 650 km and 21 degrees south of west from halifax, nova scotia. radio signals locate a ship 10.5 degrees east of south from halifax and 5.6 degrees north of east from boston. how far is the ship from each city?

sorry i really don't know what tiles and steps you are referring to

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

answer is  

d.

hope you got this right.
