Answer:
1. The Pythagoras theorem
Hypotenuse^2 = base^2 + perpendicular^2
2. Formula for calculating speed
Speed = Distance Time
3. Areas
Rectangle = length * width
Square = side^2
4. Profit and loss formulas
Step-by-step explanation:
An equation whose roots are x=3 and x=11 is
|(x-3)(x-11)|=0
We can check that, plugging in x=3 or x=11, makes both sides of the equation equal.
The area of a square is A=s2nd power,
If you could paste the answers I can do it for you.<span />
I think congruence is more for shapes while equality is more for algebra
