Answer:

a) 16

b) 36

c) 4

d) 81

Explanation:

Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

Rationalize the denominator<br><br> 11/Square root of 5 - square root of 6
olasank [31]

Answer:

-11\sqrt{5}-11\sqrt{6}

Step-by-step explanation:

The given radical expression is;

\frac{11}{\sqrt{5}-\sqrt{6}}

We multiply both the numerator and the denominator by the conjugate of

\sqrt{5}-\sqrt{6} which is \sqrt{5}+\sqrt{6}

\frac{11(\sqrt{5}+\sqrt{6})}{(\sqrt{5}-\sqrt{6})(\sqrt{5}+\sqrt{6})}

The denominator is now difference of two squares;

\frac{11(\sqrt{5}+\sqrt{6})}{(\sqrt{5})^2-(\sqrt{6})^2}

Simplify:

\frac{11(\sqrt{5}+\sqrt{6})}{5-6}

\frac{11(\sqrt{5}+\sqrt{6})}{-1}

-11(\sqrt{5}+\sqrt{6})

-11\sqrt{5}-11\sqrt{6}

Step-by-step explanation:

You can find a ratio between the two triangles based on what you're given.

If LM ~ OP the ratio is 42/14 which = 3

So if MN ~ ON and ON = 12, 12(3) = 36

Consider the inequality -5(x+7)&lt;-10. Write an Inequality representing the solution for x.
alexdok [17]

It could be 3 and lower because if you - 7 from -10 you get -17 then your equation would be -5x< -17 than you divide -17 by -5 and get 3.4 than your equation is x < 3.4 so your answer is 3.4 or below.
