Answer:

x+y=2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-10)/(5-(-8))

m=-13/(5+8)

m=-13/13

m=-1

y-y1=m(x-x1)

y-10=-1(x-(-8))

y-10=-(x+8)

y-10=-x-8

y=-x-8+10

y=-x+2

y-(-x)=2

y+x=2

x+y=2

Answer:

Perimeter: 16x + 16

Area: 40x + 15

Step-by-step explanation:

Remember, the perimeter is the sum of all the sides of a figure, it can be found by adding up all the sides. The area is the space within the figure, in the case of a quadrilateral can be found by multiplying the length by the width. Finally, in a rectangle, the opposite sides are congruent, parallel, and intersect in 90degree (right) angles.

Using this,

1. Find the perimeter

Since opposite sides are congruent, there will be two sides with a measure of ( 8x + 3 ), and two sides with the measure of 5. Hence the sum of all the sides would be

8x + 3 + 8x + 3 + 5 + 5

Add them together,

16x + 16.

The perimeter of the figure is 16x + 16

2. Find the area,

To find the area of a rectangle, multiply the length by the width.;

( 8x + 3 ) * 5

Distribute:

40x + 15

The area of the figure is 40x + 15

Answer:

The picture is attached!

Step-by-step explanation:

For c, the last bracket said (y=6) and I assumed that it is (y+6).

If it is (y-6), the answer would change, so please tell me if I am wrong.

But the rest, I hope it helps, if you have any questions, please feel free to ask me:)
