If you cut away a triangle of area 59 cm² from a square, the remaining area will be 85 cm². Find the length of the side of the s
siniylev [52]
So the square was fine, then the triangle decided to go for a hike.

now, if the triangle when it took off, it took 59 cm², and the square was left all by its lonesome with only 85 cm², that means with the triangle in it, the square is then 59 + 85 cm², or 144 cm².

\bf \textit{area of a square}\\\\
A=s^2\qquad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
A=144
\end{cases}\implies 144=s^2
\\\\\\
\sqrt{144}=s
\implies 12=s

Find all the real fourth roots of 0.0001.
Viktor [21]

Answer:

-0.1 and 0.1

Step-by-step explanation:

A fourth root is a number which multiplied by itself 4 times gives 0.0001.

Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.

0.1*0.1*0.1*0.1 = 0.0001

So the real fourth roots are -0.1 and 0.1.
