id-k but here we go

have you seen things of circles and triangles and squares? This problem is just like this. You would probably identify the squares circles and triagnles as...well....traingles circles and squares. Well, we do that but with the variables.

The numbers with 'x' is one group. And the one without it is another group. So....take 'x3' and take the x9. Because they have the same variable.

x3 + x9. (why we are adding is because it has nothing to drag with it and both of these numbers are positive)

x12!

Now do teh same with 15 and 3. Bring the plus and the subtraction sign with 3 and 15. We cant just leave them there. 15-3=12.

we have 12. this must equal 12!!!!!

The solution for b could really be any answers as long as when that number is divided by 4.3 it is less than 11.3

1 possible answer though could be 11.3

Because when 11.3 is divided by 4.3 it is less then 11.3

Sorry if I'm missing something and the answer is wrong!

Graph the function represented by the equation y=3×2-6×-9

sasho [114]

The points in the graph are (-1,0) and (3,0). I solved the equation using the Factoring method in solving quadratic equations. As I solved for finding x= -1 and 3, I substituted both to the equation in order to find y.

What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit?

Pavel [41]

see the attached figure to better understand the problem

Let

x------> the length side of a rectangle

y-------> the width side of a rectangle

we know that

the perimeter of a rectangle is equal to the formula

$P=2x+2y$
