Answer:

x=3 y= -3

Step-by-step explanation:

Add the two equations to eliminate y

4x+2y=6

x-2y=9

-------------

5x = 15

Divide by 5

5x/5 = 15/5

x = 3

Now find y

x - 2y = 9

3 -2y = 9

Subtract 3 from each side

3-2y-3 = 9-3

-2y = 6

Divide by -2

-2y/-2 = 6/-2

y = -3

Refer to the rectangle below. The length of the rectangle is x + 12. The width of the rectangle is x + 3.

Elis [28]

Answer:

$x^2+15x+36$

Step-by-step explanation:

The complete question is shown in the attachment.

The length of the rectangle is x + 12. The width of the rectangle is x + 3.

Recall that area of a rectangle is $Length \times Width$

In terms of x, the area is $(x+12)(x+3)$

Recall the distributive property of real numbers: $(a+b)(c+d)=a(c+d)+b(c+d)$

We apply this property to get:

$(x+12)(x+3)=x(x+3)+12(x+3)$

We expand again to get:

$(x+12)(x+3)=x^2+3x+12x+36$

We now simplify to obtain:

$(x+12)(x+3)=x^2+15x+36$

The area of the rectangle is $x^2+15x+36$
