Step-by-step explanation:

3x+5=4

move the positive number to the right side over the equal sign.

NB.lf the number that u moved over is positive(it as a plus sign before it ) the number will become negative when moved over the equal sign. If the number has a minus sign then when it is moved over the equal sign it becomes positive.

so for this because we have a +5.it will then be

3x=4-5

3x=-1

To get x you divide both side by 3

3x/3=-1/3

therefore x =-1/3

Which polynomial expression represents the area of the outer most square tile, shown below?

Andrew [12]

ANSWER

${x}^{2} - 6x + 9$

EXPLANATION

The outermost square tile has side length,

$l = x - 3$

The area of a square is given by;

$Area= {l}^{2}$

We substitite the given expression for the side length into the formula to obtain,

$Area= {(x - 3)}^{2}$

$Area= {(x - 3)}(x - 3)$

We expand using the distributive property to obtain;

$Area=x {(x - 3)} - 3(x - 3)$

This gives us:

$Area= {x}^{2} - 3x - 3x + 9$

$Area= {x}^{2} - 6x + 9$

The last choice is correct.
