Answer:

$( {x}^{} + 2) {}^{2} = {x}^{2} + 4x + 4$

$(2x - 3) {}^{2} = {4x}^{2} - 12x + 9$

${(3x + 4)}^{2} = {9x}^{2} + 24x + 16$

${(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2}$

${(2x + 3y)}^{2} = 4x {}^{2} + 12xy + 9y {}^{2}$

Caroline walks around a square pond with 30 m sides. Her paces are about 60 cm long. About how many paces will she take?

Elza [17]

Step-by-step explanation:

Perimeter of a square = 4 × L

L = Length of a side of the pond = 30m

Perimeter = 4 × L = 4 × 30 = 120m = 12,000 cm

Pace = 60cm

Number of paces = 12,000/60 = 200 paces

In ΔSTU, m∠S=(11x+3)∘,∠T=(2x+16)∘, and m∠U=(x+7)∘. Find .

frozen [14]

Answer:

x = 11

Step-by-step explanation:

In ΔSTU ,

m∠S = (11x+3)° ; m∠T = (2x+16)° ; m∠U = (x+7)°

According to angle sum property of a triangle , sum of all the interior angles of the triangle is 180°.

So,

$11x + 3 + 2x + 16 + x + 7 = 180$

$= > 14x + 26 = 180$

$= > 14x = 180 - 26 = 154$

$= > x = \frac{154}{14} = 11$

What is the slope of the line through points (0,6) and (5,-4)

anastassius [24]

The slope between the points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1)

(0,6) and (5,-4)
x1=0
y1=6
x2=5
y2=-4

slope=(-4-6)/(5-0)=-10/5=-2
slope=-2
