Find the quotient when x2 + 10x + 21 is divided by x + 7
1 answer:
<h3>Answer: x+3</h3>
==================================================
Work Shown:
x^2+10x+21 factors to (x+3)(x+7) since
7+3 = 10 and 7*3 = 21
Or you can use the FOIL rule to see that (x+3)(x+7) expands to x^2+10x+21
When we divide x^2+10x+21 over x+7, we get,
a pair of (x+7) terms cancel out when we divide
The quotient is x+3
The remainder is 0

Answer:
Step-by-step explanation:
For this formula it would be exponential growth. The formula for exponential growth is:
a is the initial value
r is the growth rate
t is the number of time intervals that have passed in the given situation
In this problem, you would substitute the r for the given percent (0.3) and substitute the a for 170 as the initial value. The equation would then be:
