Given a diagonal of a square, /, we are asked to find x. Assuming that x is the length of one side of the square, we can establish a relationship between the diagonal and the side. Illustrate a square and a diagonal drawn across sides:

The result is two right triangles. If x is the length of one side, the two legs of the triangle is x and x. Therefore, the diagonal is the hypotenuse. Expressing / in terms of x:

/^2 = x^2 + x^2
/^2 = 2x^2
/ = √2 x

X^- x - 6 and x^ -5x +6 what are thier common factors
Katarina [22]

I guess you mean:

X^2 - X - 6   and X^2 - 5X + 6

X^2 - X - 6 = (X + 2)(X − 3)

X^2 - 5X + 6 = (X − 2)(X − 3)

Based on that, their common factor is:

(X - 3)

Travis is cutting strips of paper for a project. He needs strips that are 114 inches wide. He cut his first strip too wide. His
choli [55]

Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

The length Travis needs to cut = 114 inches

Percent of error = 10%

Let's assume he cuts x inches wide strip

So from the percent of error formula:

\rm \dfrac{x-114}{114} = \dfrac{10}{100}

\rm x = \dfrac{114}{10}+114

\rm x = \dfrac{1254}{10}\Rightarrow \dfrac {627}{5}  or

\rm x = 125\dfrac{2}{5} \ inches  

Thus, Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches
