Answer:
3x+38
Step-by-step explanation:
1. (10x2 +5x-3)+(7x2 -2x+7) : rewrite problem
2. (20+5x-3)+(14-2x+7) : PEMDAS (10x2=20 and 7x2=14)
3. (5x+17)+(-2x+21) : PEMDAS (20-3=17 and 14+7=21)
4. 3x+38 : Combine like terms
Answer:
its 1 because -x(-1) raised to the 10 is -1 so raised to the 2 is 1
Step-by-step explanation:
Answer:
The correct answer is A) Angle 1.
Step-by-step explanation:
We know this because they are opposite of one another. The lines don't even have to be parallel for this to be true.
Answer:
V =432 cm^3
Step-by-step explanation:
The volume is given by
V = l*w*h
V = 9*4*12
V =432 cm^3
Answer:
Given speed of trolley = 125 meters per minute

Now we know that
Distance= Speed x time
Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than
Distance < 2.083 x 450 =937.5 meters
hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.
For the second case
since the time of travel is greater than 400 seconds
Thus the distance traveled is

which is greater than 800 meters.
