A because it is a pattern 4 6 4 8 and that is why it is a
Y=3x+6
y=mx+b 3 is slope and m is also the slope, six is b because it’s where it BEgins :)
Total hours of hiking is 15.12 miles
Time taken is 6.3 hours
The number of miles hiked per hour would be
Total hours ÷ time taken

=2.4 miles
So Megan has hiked 2.4 miles every hour
4c6d3 x 3c4d
4 x 3=12
12c
you add the powers so 6+4=10
12c10
d3 x d=d3
12c10d3
that is the answer i think
