Please give a worked explanation! Thanks :)

When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by $\frac{x - 2}{x - 2}$ which gets you $\frac{3x - 6}{ x^{2} - 2x}$ . Then multiply the second fraction by $\frac{x}{x}$ to get $\frac{5x}{ x^{2} - 2x}$ . Now you can add them together to get $\frac{-2x - 6}{ x^{2} - 2x}$ .

(b) $\sqrt{18} = \sqrt{9 * 2} = 3 \sqrt{2}$
$\sqrt{72} = \sqrt{36 * 2} = 6 \sqrt{2}$
now you can pull out root 2 and get $\sqrt{2}(3 - 1 + 6)$ which equals $8 \sqrt{2}$

YOU GET BRAINLIEST IF CORRECT!!!!!

It's really easy to solve this problem all you have to do is long division with 4,274 and 51.

4,274 divided by 51 is = to 83 but it still has decimals leftovers meaning there would be a remainder and since we already found out 81 is part of the answer we know it won't be 91 and it has to be 83 with a remainder!

Sketch vector v. Be sure to number your axes. Then find the magnitude of vector v. Show all work.

iren [92.7K]

Step 1

Sketch the vector V.

$v=-2i\text{ +5j}$

Step 2

Find the magnitude of the vector. The magnitude of a vector is given as;

$\begin{gathered} |v|=\sqrt{(i)^2+(j)^2} \\ i=-2 \\ j=5 \\ \left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2} \end{gathered}$ $\begin{gathered} |v|=\sqrt{(-2)^2+(5)^2} \\ |v|=\sqrt{4+25} \\ |v|=\sqrt{29} \end{gathered}$

Therefore, the magnitude is given as;

$|v|=\sqrt{29}$
