Answer:

-12.5

Step-by-step explanation:

To easily get the area of the parallelogram, we will label the vertices .

A= 1, -2.... X1, y1

B= 5,8... X2, y2

C= 3,3.... X3, y3

D= 0,8.... X4, y4

Before that, let me state that:

The Area of a parallelogram is defined as :

1/2 det (X1 (y2 - y3) + X2 ( y3 - y1) + X3 (y1 - y2)

In the order from the question:

A = (-2(8-3) + 5(3-3) + 3( 3-8)) / 2

A = -2(5) + 5(0) + 3(-5)

A = -10 + 0 - 15 / 2

A = -25/2

A = -12.5

A man travels from town x to town y at an average rate of 60 mph and returns at an average rate of 50 mph. He takes a 1/2 hour l
Georgia [21]

D/60 + D/50 = 2D/55 - 1/2

 find common denominator ( 3300)

3300/60 = 55

3300/50 = 66

3300/55=60

so then you get 55D +66D= 60(2D)-1650

121D=120D-1650

D=1650 miles

check

1650/60 =27.5, 1650/50 = 33,  27.5 + 33 = 60.5 hours total

1650/55 = 30, 30 x 2 = 60

60.5-60 = 0.5 longer

 so distance = 1650 miles
