Two buildings are 20 m apart. the angle from the top of the shorter building to the top of the taller building is 20 degrees. the angle from the top of the shorter building to the base of the taller building is 45 degrees what is the height of the taller building

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

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
