Answer:
x² - 8x - 15
Step-by-step explanation:
-4(2x + 6) + x² - 9
= -8x - 24 + x² - 9
= x² - 8x - 33
Answer: Linear model
and H'(t) = 9 units.
Step-by-step explanation:
Since we have given that
In 2000, amount spent = $100 billions
In 2010, amount spent = $190 billions.
So, rate of increase would be

So, linear model for H(t) would be

So, H'(t) would be 9.
Hence, linear model
and H'(t) = 9 units.
Answer: The area is
+ 18w
Step-by-step explanation:
We could represent the length of the yard by l = w+18 and the width as w .
And to find the area we will have to multiply the length by the width.
A= w(w+18 ) multiply
A=
+ 18w
