Answer:
We use scientific notation as sometimes numbers are so so big, that it becomes inconvenient for us to write the actual number.
Step-by-step explanation:
For example, if you have 9 billion of something, you wouldn't want to write those 9 zeroes all the time.
When writing in scientific notation we count the number of decimal places to when we have one non-zero integer to the right of the decimal place. We then write that number and multiply it by ten to the number of decimal places you counted earlier.
e.g. 4.8 X 10^7
They are the same because both triangles have the same every to the other triangle.
You'll do the (whole)(outside)= (whole)(outside) so, set it up like this: (5+3)3= (x+4)4now work it out with PEMDAS: 15+9=4x+16combine like terms: 24= 4x+16subtract the 16 from each side: 8=4xlastly, divide by 4 on each side to get x=2

Answer: x = 1
Explanation:
g(x) = 5x + 2
g(x) = 7
=> 5x + 2 = 7
5x = 7 - 2
5x = 5
x = 5/5 = 1
