What are the real solutions to the equation 5x² + 29x + 20 = 0?

Readme [11.4K]

Answer:

$x = -5,\: -\frac{4}{5}$

Step-by-step explanation:

$5x^2 +29x + 20=0$

$\implies 5x^2 +25x +4x+ 20=0$

$\implies 5x(x +5) +4(x+ 5)=0$

$\implies (x +5) (5x+ 4)=0$

$\implies (x +5) = 0,\:(5x+ 4)=0$

$\implies x = -5,\:x=-\frac{4}{5}$

$\implies x = -5,\: -\frac{4}{5}$

Find the area of the regular polygon

gregori [183]

Answer:To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

2/3 is what percent of 1/4?

saveliy_v [14]

So if we take 1/4 to be the 100%, what is 2/3 in percentage off of it then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{4}&100\\\\
\frac{2}{3}&p
\end{array}\implies \cfrac{\frac{1}{4}}{\frac{2}{3}}=\cfrac{100}{p}\implies \cfrac{1}{4}\cdot \cfrac{3}{2}=\cfrac{100}{p}\implies \cfrac{3}{8}=\cfrac{100}{p}
\\\\\\
p=\cfrac{8\cdot 100}{3}\implies p=\cfrac{800}{3}\implies p=266\frac{2}{3}\implies p\approx 266.\overline{66}$

yes, is a large value, because 2/3 is indeed larger than 1/4, more than twice as large.
