Answer:
Step-by-step explanation:
Complete the square
+ 2x - 13 = 0
+ 2x = 13
+ 2x + 
= 13 +1 (take 1/2 of the b term , the 2 )
+ 2x + 1 = 14
(x +1)^2 = 14
Answer:
they would divide it
Step-by-step explanation:
because that what some people would do
Y=3 because it is horizantal line that is between 0 and 6
Answer: 120 seconds
Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.
f'(x)=(-3x^2 + 12x)'=-6x+12=0
x=2
When x is 2, the function will reach its maximum value.
f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12
The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.
The answer is A) The student failed to properly apply the distributive property.
