An equilateral pentagon is a five-sided figure with equal side lengths. The
perimeter of an equilateral polygon can be found by multiplying the number
of sides by the length of a side. Use the Distributive Property to write a
simplified expression for the perimeter of an equilateral pentagon with side
lengths of (-4m+1) cm.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the probability is 0

c. (3,2,6) is the answer.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
