Question 1 of 29

Zina [86]

The characteristic of the repeating shapes in a tessellation is that shapes cannot have spaces between them.

<h3>What is tessellation ?</h3>

When we talk about tessellation, our minds go to a situation in which many shapes especially polygons are packed together without spaces between them.

Thus, the characteristic of the repeating shapes in a tessellation is that shapes cannot have spaces between them.

The Solution.

The given equation is

$\begin{gathered} y=|x|+7 \\ \text{Where x=11} \end{gathered}$

Substituting 11 for x, we can get the value of y.

$\begin{gathered} y=|11|+7 \\ y=11+7 \\ y=18 \end{gathered}$

Hence, the value of y is 18.

The square of a whole number 'n' lies between 80 and 150. Find all possible values for 'n'.

pychu [463]

The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.

$\sqrt{80} \approx 8.9 \\
\sqrt{150} \approx 12.2$

n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.

The possible values for n are 9, 10, 11, and 12.

How do you factor this? x^{2} + 5 x- 9 = ?

Oksanka [162]

$x^2+5x-9\\\\a=1;\ b=5;\ c=-9\\\Delta=b^2-4ac\\\\\Delta=5^2-4\cdot1\cdot(-9)=25+36=61 > 0\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\\\\sqrt\Delta=\sqrt{61}\\\\x_1=\dfrac{-5-\sqrt{61}}{2\cdot1}=\dfrac{-5-\sqrt{61}}{2}\\\\x_2=\dfrac{-5+\sqrt{61}}{2\cdot1}=\dfrac{-5+\sqrt{61}}{2}\\\\x^2+5x-9=\left(x-\dfrac{-5-\sqrt{61}}{2}\right)\left(x-\dfrac{-5+\sqrt{61}}{2}\right)$
