Answer:
D. Meters per second
Step-by-step explanation:
here's why the answer is D even though they arent the best explanations but none the less the answer is still right.
1. Newton = force
2.kilo = mass
3. foot-pound = force
4. Meters Per sec = speed/acceleration
Step-by-step explanation:
3x-2x=5+10 [taking variables on one side and constant on other]
x=15
soln:
3x-5= 2x+10
3x -5+5=2x+10+5 [ adding 5 on both side]
3x=2x+15
3x-2x=2x+15-2x [subtracting 2x on both side]
x=15
Ans=15
I believe it is A and D. All you have to do is add them all together and if both sides are the same then its a correct answer.
I realise this is quite late but in case you still wanted the answer, the width is 3m.
If the length is 3m longer than the width, you can write the width as x and the length as x + 3. The perimeter would be both lengths and both widths added together, so you would just write it as:
x + x + x + 3 + x + 3 = 18
4x + 6 = 18
- 6
4x = 12
÷ 4
x = 3
I hope this helps!
The correct answer you need will equal 9
