klemol [59]3 years ago

Answer:

(3)

Step-by-step explanation:

5x^2 - (2x-3)^2

5x^2- (2x-3)(2x-3)

now you distribute, the 5x^2 stay the same for now

So for now just (2x-3)(2x-3)

first 2x * 2x= 4x^2

2x * -3= -6x

-3 * 2x= -6x

-3 * -3= 9

So (2x-3)(2x-3) is 4x^2 -6x-6x+9

You can simplify that to 4x^2 -12x +9

Now we add in the 5x^2 from the start don't forget!

And we are subtracting sooo

5x^2 -(4x^2 -12x +9)

5x^2 -4x^2 +12x -9

x^2 +12x -9

jekas [21]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

(\stackrel{x_1}{4}~,~\stackrel{y_1}{64})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{96}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{96}-\stackrel{y1}{64}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{4}}}\implies \cfrac{\stackrel{bottles}{32}}{\underset{mins}{2}}\implies \cfrac{\stackrel{bottles}{16}}{\underset{mins}{1}}
