Find the area of the shaded region in square units. Show your reasoning.
motikmotik

Answer:

40 square units

Step-by-step explanation:

First of all, lets say that square has side l, so, the area unit is l^2

the diagonal's square is l\sqrt{2}

CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)

A_{triangles}=4*base*heigh*0.5=2*(l\sqrt{2} )(2l\sqrt{2} )=8l^2

CALCULATION OF MAIN SQUARE AREA

A_{square}=side*side=(4\sqrt{2} l)(4\sqrt{2} l)=32l^2

TOTAL AREA

A_{total}=A_{triangles}+A_{square}=8l^2+32l^2=40l^2

Which equation represents the graph?
frosja888 [35]

Answer:

The answer is A) y+4 =3(x+3)

Step-by-step explanation:

The slope is the rate of change, which you can see from the graph is m = 3/1 = 3.

Your options are given in point-slope form:

y-y1=m(x-x1)

Pick a point from the graph. I used;

(-3, -4). Now plug this into your point slope form equation.

y-(-4) = 3(x-(-3))

y+4=3(x+3)

Complete the square to transform the expression x2 + 4x + 2 into the form a(x − h)2 + k.
Nina [5.8K]

Answer:

Step-by-step explanation:

y = (x^2 + 4x)      + 2

Take 1/2 of the linear term 4/2 = 2 and square that result. 2^2 = 4.

Put it after 4x

y = (x^2 + 4x + 4)   +2  Subtract what you put inside the brackets on the outside.

y = (x^2 + 4x + 4) + 2 - 4      Combine the right.

y = (x^2 + 4x + 4) - 2            Express the brackets as a square.

y = (x + 2)^2 - 2

That's your answer

a = 1

h = 2

k = -2
