All of them are correct except for C. (4,8)
(y+5)(y+5)
-------------

Answer:
height of a cricket as it jumps
Step-by-step explanation:
this is the only thing that the value would drop over time
Ok, so this one requires you to set up an equation that makes sense....(mr. Smith + mr. Harry)/2= 489...that is the average money from the problem....ok so let’s add some variables now and make it look like math. 2x is mr smith from the first sentence. X is mr. Harry. This yields
(2x+x)/2=489.....use inverse operations to yield
2x+x=978
Combine like terms to get
3x=978
Then divide by 3
To give you x=326
What does x tell you?
X= harry = 326
2x = Smith = 652
To check add them together and divide by 2 to get the average....489
Answer:
4989600
Step-by-step explanation:
First, find how many letters there are. There is 11 letters.
Next, find which letters are repeated and if so, how many times. The letters O, R, and H are each repeated twice.
Since there are 11 letters, you must do 11 ! (factorial). There are 3 letters that are repeated twice, so you must divide by 2 ! 3 times.
Your equation is:
11!/ 2! * 2! * 2!
It simplifies into 39,916,800/8 which is equal to 4989600
