Answer:

Row 2 (B)

Step-by-step explanation:

We can find out the answer just simply by adding up each of the rows seperately and finding out which one has the highest value, since all of the rows have the same amount of spaces that you need to divide by. Row 2 has the highest value with 23.

Answer:

104 units

Step-by-step explanation:

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.

AB=\\BC=20\\CD=30\\AD=

A'B'=22\\B'C'=\\C'D'=\\A'D'=32

Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:

AB=22\\BC=20\\CD=30\\AD=32

A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32

See? Notice how the values are the same! To find the perimeter (P) of a quadrilateral, we have to add each side length:

P=22+20+30+32

Solve:

P=104

Which is an equation in point-slope form for the given point and slope?
Akimi4 [234]

Answer:

The answer to your question is the letter D. (step 2)

Step-by-step explanation:

Data

P (7, 4) slope = 6

Process

1.- Write the equation of the line

          y - y1 = m(x - x1)

   x1 = 7    y1 = 4

2.- Substitution

          y - 4 = 6(x - 7)

- Simplification

         y - 4 = 6x - 42

- Solve for y

         y = 6x - 42 + 4

         y = 6x - 38        This is the equation in the point-slope form

3.- According to the choices the answer is letter D.
