you find what they both divide by and then divide each one and then you keep doing that until you cant no more
Well you already know your side lengths, so you use this formula S=1/2(A+B+C). For A put in one of your side lengths, for B put one of your side lengths, and for C put one of your side lengths. After you do that solve. But your not done. Once you find out what S equals by doing the formula I just showed you, you have to do another formula which is A= S(S-A)(S-B)(S-C). Once again plug in your side lengths for A,B, and C but then plug in your S value. (Remember you already found your S value by doing the first formula I showed you). Then do the math and then you will find your answer.
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.
Answer:
I made the problem in a photo so you could do it for the next
-225/-15 will give us a positive answer since we are dividing by two negative values, so we can rule out answers 1 and 2 first off.
then we solve to find the answer -225/1*-1/15 = 15
hope this helps! thanks!
