Hey there!!

General formula:

(a-b)² = a²-2ab+b²

We have:

... (a-b)(a-b)

This could be written as (a-b)²

Hence, the answer is :

... (a-b)² or a²-2ab+b²

Hope my answer helps!

5r^2-13r-6=0 How do I solve this

frosja888 [35]

$5 {r}^{2} - 13r - 6 = 0 \\ a = 5 \\ b = - 13 \\ c = - 16 \\$

r= -(-13)±>

$\sqrt{( - 13) {}^{2} } - 4.5( - 6)$

2.5

r= 13±17

10

r=13+17

10

r=13-17

I need assistance with "What does the area of the rectangle depend on", the graph section, and the relationship section.

DanielleElmas [232]

The area equation here is:

$A=2w^2$

That means that the area depends on the width measurement of the rectangle.

To graph a quadratic function you have to see if the parabole is positive and the transformations, in this case, are positive and have a multiplication by two, which means that the graphics in x=1 and x=-1 will be y=2

Finally, you can conclude that there, you have a relationship between the area and the width of the rectangle because is a quadratic relationship and the area will increase in a quadratic form according to the increase of the width.

Answer:

NO WAIT NO IGNORE MY PREVIOUS ANSWER

NOT A FUNCTION

If you draw vertical lines on the dotted line, one line will intersect two parts of the dotted line, so it is not a function.
