Answer: 70

Step-by-step explanation:

Because opposite sides of a parallelogram are equal, AB=CD. So,

2x-10=x+30

x=40

Therefore, AB=2(40)-10=70

To which set(s) of numbers does the number sqrt -16 belong? Select all that apply.
Mice21 [21]
<span>The square root of -16 is an imaginary number and a complex number. Sqrt(-16)=4i. We use the i to indicate that the number is imaginary since there is no number that can be multiplied by itself to get a negative number (a negative times a negative is a positive, and a positive times a positive is also a positive). So the use of i tells you immediately that it's an imaginary number. You can tell the number is complex because it has both a real and an imaginary part and could be written in the form a+bi, where a is a real number and bi is an imaginary number. In this specific case, the real part (a) is 0 and the imaginary part (bi) is 4i.</span>

I’m guessing this is a trick question, but I’m gonna go with what I think

Answer: She would have to pay 58 in a month if she downloaded 50 songs with the subscription from the streaming music services. She’d pay 50 dollars for 50 songs, since one song costs a dollar.
