we were given this problem by my maths teacher.basically just tell me what is wrong with this :
a=b+c
a(a-c)=(b+c)(a-c)
a2-ac=ab-bc+ac-c2
a2-ab-ac=ac-bc-c2
a(a-b-c)=c(a-b-c)
a=c



come on have a go !!!

Everyday, when I return from work there are at least 5 dragonflies on the house. But this seems to be the case everywhere I go. Plus, i saw a news headline on TV last week but i didn't have time to watch the news so I missed out on why there are so many dragonflies.

The mass and acceleration of an electron are measured and the following data are collected, in the scientific notation.
() = it's normal replace the thing type in small on the head of the number. i think it's the power of

mass of electron = 9.10*10(-31)kg
acceleration of the elctron =2.4*10(2)m/s(2)

You know that force = mass x acceleration. What is the force on the electron?

Given:

The family has 6 children and one of them is a male

Question:
What is the probability that the family has 4 males and 2 females?

The answer is 5/21. Can anyone tell me how to get this answer using formula? (You shouldn't list all the possible combinations then count the number)

Initially the box is at rest. Person pushes box gently, but gradually increases the force so the force exerted on the box varies in time as F = (8.6 N/s)t. After 3 s they stop pushing the box. Force is always exerted in the same direction.
How far have they pushed the box in 3 s (answer in m)?
What is the velocity of the box after 3s (answer in m/s)?

Please include how you did it
The Basal metabolic rate is the minimal metabolic activity of a person at rest, for an adult this is 1.2 Cal/min. How many calories must a person consume in one day (24 hours) to meet the requirements of this bsal metabolic rate
