Answer: 
==================================================
Explanation:
We simply add the expressions we are given, though we cannot combine the terms (as they aren't like terms). There's not much to show in terms of steps, though I guess you could have the following:

Adding 4 onto 2^x means we shift the 2^x curve up four units.
Answer:
Step-by-step explanation:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:cos x = BC / ySolving for BCBC = y cos xBC is the distance between the Earth and the Sun

Part A:You'll put 8 books on each shelf.
To do this, all I had to do was find the greatest common factor(GCF) of 32 and 56 which is 8. You have to do that because you had to find a number that divided evenly between 32 and 56.
Part B: Mystery Books:4
Biography Books: 7
Answer:
see below
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
5x+60 + 3x-40 = 180
Combine like terms
8x +20 = 180
Subtract 20 from each side
8x+20-20=180-20
8x= 160
Divide by 8
8x/8=160/8
x=20
5x+60 = 5*20+60 = 160
3x-40 = 3*20-40 = 20
