Answer:
Box 2
Step-by-step explanation:
A graph shows that 3x^2 > (4x^2 -x) only between x=0 and x=1. Thus, Box 2 has a larger base area for all other values of x.
Box 2 is likely to take up more space if x is unlikely to be between 0 and 1.
Answer:
B. first step
6/7x=7/8-1/2
c. second step
6/7x=7/8-4/8=3/8
d. and e are the same
