Answer:

The length if the pool is 12

Step-by-step explanation:

Formula: A=lw or lw=A

> (x+4)(x-2)=72

> (x²-2x+4x-8)=72

> x²+2x-8=72

> x²+2x-8-72=0

> x²+2x-80=0

Factor

> x²+10x-8x-80

> x(x+10)-8(x+10)

>(x+10)(x-8)

Check:

(x-4); (x-2); x=8

(8+4)=12 Length

(8-2)=6 Width

Use a inequality symbol to compare -3x+7 -10-2
abruzzese [7]
Hey there,

Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).

So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)

Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7). 

    -3
+   7
______
     4

Let's bring that "x" back, and the answer would be 4x for a while.

So far, 4x is the answer.
_____________________________________________________________

Now, Let's work on the other side.

We are talking about (<span>-10-2)

    -10
-      2
_______
</span>     -12

So, by solving the answer to (-10-2), we got -12.

So, let's determine what is greater . . . . . 

What \ is \ greater?

-12 or 4.

-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.

Your correct answer would look like . . . 

<span>(-3x+7) > (-10-2)
</span>
I really hope this helps you alot.
