Answer:
16m^2-40mn+25n^2
Step-by-step explanation:
This is using (a-b)^2= a^2-2ab+b^2
Now if you replace a with 4m and b with 5n you will get 16m^2-40mn+25n^2
He climbed 3/4 of a mile in 2/3 of an hour.
Now we're getting somewhere.
Speed = (distance) / (time)
Speed = (3/4 mile) / (2/3 hour)
Speed = (3/4) / (2/3) mile/hour
Speed = (3/4) x (3/2) mile/hour
Speed = 9/8 mile/hour
<em>Speed = 1 and 1/8 mile/hour</em>
That's Choice-C.
