Answer:

5x = x^2 - 6

Step-by-step explanation:

<em>a number</em> can be represented by x,

<em>5</em><em> times a number</em> can be represented as the product of 5 and x, <em>6</em> <em>less than the square of that number</em> tells us that this is equal to a number squared minus 6. <em>is</em> tells us that these two expressions are equal.

If you want a working number, just solve by completing the square once this is in standard form. This is then converted to vertex form.

x^2-5x-6 = <u>(</u><u>x-5</u><u>/</u><u>2</u><u>)</u><u>^</u><u>2</u><u>-</u><u>4</u><u>9</u><u>/</u><u>4</u> = (x^2-5x+25/4) -49/4 = x^2-5x-6.

(x-5/2)^2-49/4=0

(x-5/2)^2=49/4

(x-5/2) = ±√49/4

(x-5/2) = ±7/2

x=5/2±7/2

x=(5±7)/2

x=12/2,-2/2

x=6,-1

Thus, the number can either be 6 or -1.

Proving That All Circles Are Similar
Nitella [24]

Answer:

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.
