Answer:

8 - 42x - 56y - 12xy

Step-by-step explanation:

<u>Given sides of a rectangle</u>

Length: l =4 − 7(3x + 4y)
Width: w = 3x(−2y)

<u>Perimeter of rectangle</u>

P = 2(l + w)

<u>Using the given values</u>

P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
2( 4 - 21x - 28y - 6xy) =
8 - 42x - 56y - 12xy

what is the general form of the equation of a circle with its Center at -2 1 and passing through -4 one

blondinia [14]

Answer:

$\large\boxed{x^2+y^2+4x-2y+1=0}$

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

The general form of an equation of a circle:

$x^2+y^2+Dx+Ey+F=0$

We have the center (-2, 1). Substitute to the equation in the standard form:

$(x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2$

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

$(-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4$

Therefore we have the equation:

$(x+2)^2+(y-1)^2=4$

Convert to the general form.

Use $(a\pm b)^2=a^2\pm 2ab+b^2$

$(x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\qquad\text{subtract 4 from both sides}\\\\x^2+y^2+4x-2y+1=0$
