Step-by-step explanation:
Arc length = radius × angle
s = r θ
60 cm = 20 cm × θ
θ = 3 radians
Answer/Step-by-step explanation:
Recall: 
a. 
b. 
c. 
So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:

Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: 
<u>Now you can rewrite this as
, which is your final answer.</u>
Answer:
C:2 gallons per minute
Step-by-step explanation:
Answer:
(x + 2)^2 - 11.
Step-by-step explanation:
f(x) = x^2 + 4x - 7
Now x^2 + 4x = (x + 2)^2 - 4 so we have:
f(x) = (x + 2)^2 - 4 - 7
f(x) = (x + 2)^2 - 11.
