Step-by-step explanation:
year 1 : 18 in
every year after that he grows 3 in so 3 in so 3x9=27
then 27+18=45
Answer:
Both of the equations are right because if you take s=4p, then reverse it, p=1/4 of s because 4 of p is equal to s so s/4 = p
Just make a triangle and an X and Y axis and reflect it over the Y axis. It's that simple. Then tell how you did it. Obviously it will be a reflection. Name the points (before and after) and you are done.
