Answer:
36 units
Step-by-step explanation:
P = 12 + 12 + 6 + 6
picture the shaded semi-circle filling in the unshaded semi-circle and you have a 6 by 12 unit rectangle

3/12 = 0.25 This is a terminating decimal, as the decimal has a finite number of digits.
2/9 = 0.222222... This is a repeating decimal, as there is no end to the number of digits.
I think it is 25% but you need to work out ;)
<span>The equation that gives the speed of the boat after David has rowed for x hours is </span><span>y=4-1.5x.

The direction David is rowing (upstream) is the positive direction. That makes the direction the river is flowing negative.
David rows at 6 mph, but the river is flowing at 2 mph in the opposite direction. That means his "net" speed, relative to an observer on the ground, is 6-2 = 4 mph.
He loses 1.5 mph of his speed every hour, so after x hours, his speed is 4-1.5x.
