Answer:

This is a rectangle, so if AB is equal to 3 centimeters, then DC is equal to 3 centimeters.

Since Angle X is equal to 45 degrees, then angle CDE, is also equal to 45 degrees, and we have an isosceles triangle, since angle CDE and DEC are equal to each other.

This means, that CE = DC.

And because E is the midpoint of CB, CE = EB.

So basically, we have:

DC = CE = BE

DC = 3

3 = CE = BE

And we see that CE and BE are both equal to 3, which makes CB equal to 6, which makes solving the area easy. (3 x 6), which is 18.

B is correct!

murzikaleks [220]

Answer: B

Step-by-step explanation: option B would be a better deal than option a because if you go off went golfing and use option a every month and paid $25 It would add up to $85 a month so it’s better to do b and option a would be a better deal if you only went golfing one time a month. I hope this makes sense!

What is the solution set of [1/x-2]<-2

BigorU [14]

Answer:

3/2 < x < 2

Step-by-step explanation:

We assume the problem is ...

[tek]\dfrac{1}{x-2}<-2[/tex]

This will not be true for x-2 > 0 because that would make the left side positive. So, we must have x < 2, which makes the denominator negative. Multiplying by (x-2), we get ...

1 > -2(x -2)

1 > -2x +4

2x > 3 . . . . . . add 2x-1

x > 3/2

From above, we also have x < 2, so the solution set is ...

3/2 < x < 2
