Answer:
M = 7x² +21
Step-by-step explanation:
Subtract the unwanted terms on the left from both sides.
(-7x² +6x -16) + M = 6x +5
M = 6x +5 -(-7x² +6x -16)
M = 7x² +21 . . . . simplify
Hey! Good Morning! (if its morning for you) Easy way to figure these things out is to just graph them an take a look. Since we know this is a parallelogram, we can use the basic rules of them to know for sure where that one last point is. (Or we can use the first way, your choice) So just by graphing those points and looking at the incomplete stricter it created,
We can know the last point lies at (0, 2) (I put this spaced so you don't have to read my entire message lol) Hope this helps and good luck!
B. 54 meters
first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.
then use formula for perimeter
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54<span />
A equivelint ratio is when u can multi or divide by both sides
