I’m pretty sure he could only make 1 rectangle with 5cm because it’s an odd number which means he couldn’t stack them on top of each other evenly like he could with the 6cm rectangles, so he’d only be able to line them up next to each other and that’s it (I hope that’s right; sorry if it’s not but it makes sense to me lol)

Rationalize the numerator. <br><img src="https://tex.z-dn.net/?f=%20%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B144x%20%7D%20%7D%7B%20%5Csq

Simora [160]

rationalizing the numerator, or namely, "getting rid of that pesky radical at the top".

we simply multiply top and bottom by a value that will take out the radicand in the numerator.

$\bf \cfrac{\sqrt[3]{144x}}{\sqrt[3]{y}}~~
\begin{cases}
144=2\cdot 2\cdot 2\cdot 2\cdot 3\cdot 3\\
\qquad 2^3\cdot 18
\end{cases}\implies \cfrac{\sqrt[3]{2^3\cdot 18x}}{\sqrt[3]{y}}\implies \cfrac{2\sqrt[3]{ 18x}}{\sqrt[3]{y}}
\\\\\\
\cfrac{2\sqrt[3]{ 18x}}{\sqrt[3]{y}}\cdot \cfrac{\sqrt[3]{(18x)^2}}{\sqrt[3]{(18x)^2}}\implies \cfrac{2\sqrt[3]{(18x)(18x)^2}}{\sqrt[3]{(y)(18x)^2}}\implies \cfrac{2\sqrt[3]{(18x)^3}}{\sqrt[3]{18^2x^2y}}$

$\bf \cfrac{2(18x)}{\sqrt[3]{324x^2y}}~~
\begin{cases}
324=2\cdot 2\cdot 3\cdot 3\cdot 3\cdot 3\\
\qquad 12\cdot 3^3
\end{cases}\implies \cfrac{36x}{\sqrt[3]{12\cdot 3^3x^2y}}
\\\\\\
\cfrac{36x}{3\sqrt[3]{12x^2y}}\implies \cfrac{12x}{\sqrt[3]{12x^2y}}$

Find the measure of CD⎯⎯⎯⎯⎯⎯⎯⎯.<br><br> A. 8<br> B. 6<br> C. 5<br> D. 7

oee [108]

Answer:

Using the property of intersecting secant:-

$(DE)(CE)=(FE)(LE)$

$(4)(x-1+14)=(5)(x-4+5)$

$4(x+3)=(5x+1)$

$4x+12=5x+5$

$4x+-5x=5-12$

$-x=-7$

$x=7$

$So, CD=x-1=7-1=6$

$so,~your ~answer ~is ~B) ~6$

This number is 0.02 more than five and five tenths

Nadya [2.5K]

5 and 5/10s sounds like 5.5 so I'd do 5.5+0.02=5.52

Solve for x In the triangle

Goryan [66]

$\boxed {\boxed { \sin(\theta) = \dfrac{\text{opp}}{\text{hyp}} }}$

$\sin(38 \textdegree) = \dfrac{x}{11}$

$x = 11 \times \sin(38 \textdegree)$

$x = 6.8 \text { units}$
