(7w^2-7w-8)-(5w^2+2w-3)= 7w^2-7w-8-5w^2-2w+3=7w^2-5w^2-7w-2w-8+3=2w^2-9w-5
All of them would be true so I would say the answer would be D.
hope that helped.
Answer: Your company would ship 1,800 packages in 4 days
Step-by-step explanation: 450 multiplied by 4 equals 1,800
1. To <span>Calculate the resultant speed of the plane, you need to find the speed of the air, add it to the plane speed, then find the resultant using trigonometry.
</span>
The velocity of the plane:
east=400 knots
The velocity of the air
50knots north east = 50/√2 north + 50/√2 east
The resultant speed would be:
total speed^2= east^2 + north^2
total speed= √(400+50/√2)^2 + (50/√2)^2
total speed= √(189534.254 + 1250)
total speed= 436.8 knots
2. To count the direction of the plane, you need to find the total speed of x(east/west) and y(north/south) axis separately then use tan formula.
east speed= 400knots + 50/√2 knots= 435.35 knots
north speed= 50/√2knots= 35.35 knots
tan a= opposite/adjacent
tan a = north speed/ east speed
tan a= 35.35/ 435.35
tan a=0.0812
a= 4.6 degrees
Answer:
Step-by-step explanation:each bag has 7 flower stickers........I think
we multiplicate 9*5 that is 45
9-2 is seven ,seven flower stickers
