What property for 5(3x-6/7)

5(3x-6/7)

1) 5×3x=15x

ii)5×-6/7=-30/7

2)15x=-30/7 3)15x/15=-30/7/15 (4)x=-2/7or -

0.9

steps

1)multiply 5 with what you have in the bracket.

2)divide both sides by15 to get the value of x

3)and whatever you get is the answer.

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)

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
