Step-by-step explanation:
8x^3+2x-2+9x^2-7+2x-2x^3 - Combine like terms
10x^3+9x^2-9
Answer:
Late response, sorry. It is 750 meters.
Step-by-step explanation:
An easy method to save time is to just divide the distance by time to find what amount per second it can run. In this case, you have 120 and 4 to work with. Divide and you'll get 30 meters per second. Then, multiply 25(your seconds) by 30(the meters it runs per second) to get your answer.
Answer:
A, B and C (close examination)
Step-by-step explanation:
A. 15m3 - 6m = 3m(5m2 - 6m)
B. 40m6-4=4(10m6-1)
- 0 = 0
- All real numbers are solutions
C. 6m2+18m=6m2(1+3m)
D. 32m4+12m3(8m+3)
This is tough one but I will explain this problem by close examination:
The problem is looking for an equation that have the variable m by itself
D is out of the picture because the equations does not have m by itself
Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)
By close examination, The answer are A, B, and C.
A.
1 meter = 3.28 feet
Height = 199 / 3.28
Height = 60.6707 m
To the nearest hundredth = 60.67 m
B.
1 Kilometer = 1000 meter
1 meter = 3.28084 feet
1 kilometer = 3280.84 feet
Length = 26,372 / 3280.84
Length = 8.0382 km
To the nearest hundredth = 8.04 km<span />
65 kg i think or 143 pounds
