Answer:

P = -12xy - 56y - 42x + 8

Step-by-step explanation:

P = 2L + 2W

P = 2(4 - 7(3x + 4y)) + 2(3x(-2y))

P = 8 - 14(3x + 4y) + 6x(-2y)

P = 8 - 42x - 56y - 12xy

P = -12xy - 56y - 42x + 8

____ [38]

Answer:

A) $\frac{wx}{6}$

Step-by-step explanation:

$\frac{3wx}{6x}\cdot \frac{3wx}{9w}$

Multiply:

$\frac{3wx\cdot \:3wx}{6x\cdot \:9w}$

Cancel off the common factor "w":

$\frac{3x\cdot \:3wx}{6x\cdot \:9}$

Cancel off the common factor "x":

$\frac{3\cdot \:3wx}{6\cdot \:9}$

$\frac{9wx}{54}$

Cancel off the common factor "9":

$\frac{wx}{6}$

A circle in the xy-plane has its center at the point (-6,1). If the point (7, 12) lies on the circle,

Delicious77 [7]

Answer:

radius ≈ 17.0 units

Step-by-step explanation:

The radius is the distance from the centre of the circle to a point on it.

Calculate the radius r using the distance formula

r = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)

r = $\sqrt{(7+6)^2+(12-1)^2}$

= $\sqrt{13^2+11^2}$

= $\sqrt{169+121}$

= $\sqrt{290}$ ≈ 17.0 ( to the nearest tenth )
