Ussed = x
biked = 75 + x
total trip = 325 = x + (75 + x)
325 = 75 + 2x
250 = 2x
x = 125
<span>biked = 75 + x = 75 + 125 = 200 km</span>
Answer:
see below
Step-by-step explanation:
a) 2 2/3 = (2 x 3 + 2) / 3 = 8/3
area = 3/4 x 8/3 = 24 / 12 = 2
b) perimeter = (2 x 3/4) + (2 x 8/3) = 6/4 + 16/3 = 18/12 + 64/12 = 82/12 = 41/6
No because one will be 36 inches the other will be 36 centimeters they dont equal the same measurements

Answer:
4a +4
Step-by-step explanation:
The average rate of change of f(x) on the interval is ...
(f(a) -f(1))/(a -1)
= ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)
= 4(a² -1)/(a -1) = 4(a +1) = 4a +4
The average rate of change on the interval is 4a +4.
