20/1.04 = 19.60$
20.00$-19.60 = 0.40$ in change.
Answer:
2x-3+x+x+3=36
Step-by-step explanation:
since perimeter is all the sides added together and the total perimeter is 36.
Consider two pairs of coordinates (x₁, y₁) and (x₂, y₂), the mid-point of these coordinates are
![( \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )](https://tex.z-dn.net/?f=%28%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%20%2C%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%20%29%20)
We have midpoint (-1, 7i) and one pair of coordinate (3, 8i)
The other pair of coordinate would be given by
![( \frac{x_1+3}{2}= -1, \frac{y_1+8}{2} =7)](https://tex.z-dn.net/?f=%28%20%5Cfrac%7Bx_1%2B3%7D%7B2%7D%3D%20-1%2C%20%5Cfrac%7By_1%2B8%7D%7B2%7D%20%3D7%29)
The value of x is (2 × -1) - 3 = -2 - 3 = -5
The value of y is (2 × 7) - 8 = 14 - 8 = 6
The value of x represents the real part
The value of y represents the imaginary part
The other coordinate is (-5, 6i)
