Answer:
TRY 416in²
Step-by-step explanation:
front:
8×17=136÷2=68
same for the back
back = 68
side 1=
7×15=105
side 2=
8×7=56
bottom=
17×7=119
68+68+105+56+119=416
Answer:
The simplified expression is 
Step-by-step explanation:
The given expression is:

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

Divide both the numerator and the denominator by 12b:

The expression finally becomes:

distance = rate * time
2.56 meters = 2meter/min * t
divide by 2 on each side
2.56/2 =t
1.28 minutes =t
