What is a simpler form of the following expressions?
(7p -8)(7p + 8)
a. 49p^2 + 112p + 64
b. 49p^2 - 112p - 64
c. 49p^2 + 64
d. 49p^2 - 64

D. 49p² - 64

Step-by-step explanation:

(7p - 8)(7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b)(a + b)

Then the solution must be a² - b²

Considering (7p - 8)(7p + 8) then the answer is;

(7p)² - 8² = 49p² - 64

only 10/60 isn't equivalent

hope this : )

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
