simplify 15/39
Answer:
If Brianna's (I'll call her Bri in this situation) teacher says 3r + 5 and 4r are equal, you should definatly start by adding the 'r' value to the 3, which would be 8 afterwards. Bri is then incorrect because 4+5=9, and 9 is greater than 8, so Bri is wrong :'(...
Have a good day fellow lad,

1:4 is you answer. 4-3 is 1 and you do the same to 7
Answer:
-20p^5q^5
Step-by-step explanation:
20p^5q^5 that's your answer
You have to complete the square on this to get it into standard form of a circle. Move the 8 over to the other side because that's part of the radius. Group together the x terms, take half the linear term which is 8, square it and add it in to both sides. Half of 8 is 4, 4 squared is 16, so add in 16 to both sides. I'll show you in a sec. You don't need to do anything to the y squared term. This just means that the center of the circle does not move up or down, only side to side, right or left. Here's your completing the square before we simplify it down to its perfect square binomial.

. Now break down the parenthesis into the perfect square binomial and do the addition of the right:

. This is the standard form of a circle that has a center of (4, 0) and a radius of
