Answer:
Step-by-step explanation:
We need to analize the exercise.
We know that the sales-tax rate in your state is 4.5% and the cost of the CD is $18.50.
Then, let be "x" the the amount of sales tax you will pay for the CD.
You can write this expression:
Evaluating, you get that the value of "x" is:
9514 1404 393
M = (0, 0), which IS the origin
The midpoint is given by the formula ...
M = (A + B)/2
M = ((4, -6) +(-4, 6))/2 = (4-4, -6+6)/2 = (0, 0)/2
M = (0, 0) . . . . . IS the origin
AB=CD
AD=BC
AB=2X+8
CD=3X+4
2X+8. =3X+4
3X-2X.=8-4
X=4.
AD=X+17
=4+17
=21
BC=21
