Answer:
The first one is missing (d - 9) so it would be 5(d -9) or when you factor it out 5d - 45
In the second one (d + 7) is missing so it will be 8d(d + 7) so if you factor that out you will receive 8d^2 + 56
Step-by-step explanation:
3d^2 + 18d -21 =(3d -3)( d + 7)
3d^2 -30d +27 =(3d -3)(d - 9)
Connie made 60 throws and Sarah made 72.
Answer:
36 pieces
Step-by-step explanation:
4 1/8 ft x 4 1/8 ft = 49.5 in x 49.5 in = 2450.25 in^2
8.25 in x 8.25 in = 68.06 in^2
2450.25/68.06 = 36 pieces
checking for scrap loss:
49.5/8.25 = 6
so no scrap loss
Answer:
• From trigonometry ratios:
- opposite → 28
- hypotenuse → 35
Answer:
360 mi/h
Step-by-step explanation:
The speed for the outbound trip was ...
speed = distance/time = (715 mi)/(2 1/6 h) = 330 mi/h
The inbound speed was ...
(715 mi)/(1 5/6 h) = 390 mi/h
The airspeed of the plane is the average of these two ground speeds, so is ...
(330 +390)/2 = 360 . . . . mi/h
