Negative 3 + 2 (2 x + x + 3) Step 1: Negative 3 + 2 (2 x + 2 + 3)
Step 2: Negative 3 + 2 (x + 5)
Step 3: Negative 3 + 2 x + 10
Step 4: 2 x + (negative 3) + 10
Step 5: 2 x + 7

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 equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
