This is the answer to your following question. Good luck!
4 - (-13) = 17
Hope this helps!
Answer:
A= ( 5 x 3 ) x [(9-5)x3 divided by 2]
15+6
=21
P= 5+5+3+9
=22
5*5 = 25
5*9= 45
5*1= 5
25 dollars now add the cents
now it is $25.50
At x = -4 and -8
Take the derivative of the given equation to find rate of change of the graph.
f'(x) = 6x^2 + 72x + 192
At a horizontal tangent, f'(x) = 0, so set the equation equal to 0 and solve. Eventually you get x = -4 and -8
