Answer:
1260 inches squared
Step-by-step explanation:
Bottom: 24*6=144
Bottom front: 24*12=288
Bottom back: 24*12=288
Left side: 6*2=72
Right side: 6*12=72
Left top: 6*15=90
Right top: 6*15=90
Top front: (24*9)/2=216/2=108
Top back: (24*9)/2=216/2=108
144+288+288+72+72+90+90+108+108=1260
Answer:
Step-by-step explanation:
Info is missing from #29; please supply it.
The two lines shown in #30 intersect at (0, 2), which is the solution, and is also the y-intercept of both lines.
#31: Combine -5ab and 3ab; we get -2ab. To this add 6b:
-2ab + 6b (answer)
#32: Combine the n terms. We get 9 + 7n = 16.
Consolidate the constants: 7n = 7
Solve for n: n = 1

Answer:
170 mph
Step-by-step explanation:
The speed of the airplane can be represented by s. The travel time will be ...
time = distance/speed
925/(s +15) = 775/(s -15)
925(s -15) = 775(s +15)
150s = 25500 . . . . . . . . . add 13875-775s
s = 170
The rate of the plane in still air is 170 mph.
