In your own words, describe how Carla's construction steps will be different from Daryl's construction steps?

They can be different because Daryl is doing it online so he will not have to swing arcs on the computer screen he will just use circles.  Hope that this helps!

4a^2+6x-3

Step-by-step explanation:

3m-4n +7p

-5m +9n -6p

+7m -6n -5p

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

Combine like terms

3m-4n +7p

-5m +9n -6p

+7m -6n -5p

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

(3-5+7)m  +(-4+9-6)n  +(7-6-5)p

5m-n-4p

a^2  -3x +1

a^2   +9x -6

2a^2 +0x +2

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

Combine like terms

a^2  -3x +1

a^2   +9x -6

2a^2 +0x +2

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

(1+1+2)a^2 +(-3+9+0)x +(1-6+2)

Find the coordinates of the intersection of the medians of △ ????BC given ????(2, 4), ????(−4, 0), and ????(3, −1).
Damm [24]

Answer:

The coordinates of the intersection of the medians of △ABC is (1/3, 1).

Step-by-step explanation:

Consider the vertices of △ABC are A(2, 4), B(−4, 0), and C(3, −1).

Intersection of the medians of a triangle is known as centroid.

Formula for centroid of a triangle is

Centroid=(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3})

Using the above formula the centroid of △ABC is

Centroid=(\dfrac{2-4+3}{3},\dfrac{4+0-1}{3})

Centroid=(\dfrac{1}{3},\dfrac{3}{3})

Centroid=(\dfrac{1}{3},1)

Therefore the coordinates of the intersection of the medians of △ABC is (1/3, 1).

Find the area of the following shape. you must show all work to receive credit.
Margaret [11]

Answer:

<h2>A = 57</h2>

Step-by-step explanation:

Use the Pick's theorem

Let P be a polygon in the plane whose vertices have integer coordinates. Then the area of P can be determined just by counting the lattice points on the interior and boundary of the polygon!

In fact, the area is given by

A=i+\dfrac{b}{2}-1

where <em>i</em> is the number interior lattice points, and<em> b</em> is the number of boundary lattice points.

Look at the picture.

i=50,\ b=16

Substitute:

A=50+\dfrac{16}{2}-1=50+8-1=57
