Answer:
2x + 5
ok.. slightly silly question...
you will eventually learn that this formula is the
formula for the "derivative" in calculus....
A
becomes (a*b) 
2x + 5
Step-by-step explanation:
Answer:
C none of the above
Step-by-step explanation:
x + z + y
is not going to be equal to x + y - z
Its like saying 10 + 5 - 4 = 11
To 10 + 5 + 4, they are not going to be equal
Let x be the common ratio and y be the 3rd term
11.25/x=y This means the fourth term divided by the common ratio will get the third term
20x=y This means the second term multiplied by the common ratio will get the third term
11.25/x=20x Set the two y's equal to each other, and solve for x!
20x^2=11.25
x^2=.5625
x=+-√.5625
x=.75 or -.75
