But I do not know how to convert that into a perimeter. And I need to know this! What do I do. I know that the equation is perimeter is 4 times the square root of the area. But I need to know why in order to pass the explanation requirement on the CIM test for school. So if anyone can eloborate or verify that formula! That would be AWESOME! Thanks :)Answer Question

A region G is formed from a 1 × 1 square by
removing a r × r square from one corner. (Here 0 < r < 1.)
• What is the largest square that fits entirely inside G ?
Justify your answer.
(The obvious choice is to fit a square of side (1 – r) into G.
But could some tilted square possibly have larger area? Explain.

NOTES: I know that the biggest square is (1-r)(1-r). However, how do you calculate the area of the tilted square?

The square root of 6 is approximately 2.45.

You get two separate answers because in one, you add 2.45 and in the other you subtract it.

One is -7 + 2.45 = -4.55

The other is -7 - 2.45 = -9.25

the square root of 36 is 6 why? because 6 times 6 = 36
the square root of x^6 will be x^3 because x^3 times x^3 = x^6 (remember when u multiply base the exponents are added

therefore square root of 36x^6 will be 6x^3

Hope this Helps!

(x plus.minus root 12 ) = plus.Minus root 10
now you have 4 cases that
1. + +
2. + -
3. - -
4. - +
answers are
1. Root 10- root12
2. -Root 10- root12
3. -Root 10 +root12
4. Root 10 + root12

x^2 + 6x + c
= x^2 + 6x + 9 - 9 + c
= (x + 3)^2 + (c - 9)

What do you mean "solve"? Do you want the roots?
(x + 3)^2 + (c - 9) = 0
(x + 3)^2 = 9 - c
x + 3 = +/- sqrt(9 - c)
x = -3 +/- sqrt(9 - c)
