This is called difference of squares. It's like
a^2-b^2=(a-b)(a+b)
t^2-25=(t-5)(t+5)
Hope this helps :)
X^2 + 6x + 9
x 3
x 3
(x+3) (x+3)
x^2 + 3x + 3x + 9 (FOIL method)
x^2 + 6x + 9 (true)
your answer is 9 as the constant
hope this helps
Answer:

Step-by-step explanation:
Given

Where



Substitute these values in the above formula:




Answer:
Three days at the most.
Step-by-step explanation:
First you must see how much money he spends on driving, 75 x 0.10 = 7.5. Subtract that from 120 to get 112.5. He has that much money left. Now you will divide 112.5 by 30.05. 112.5/30.05 = 3.74376039933. Simplify to get 3.
(also, he will have 22.35 dollars left)
A = 804.25
B = 678.58
Cylinder A is bigger than Cylinder B
