Determine the length of the legs in the right triangle below.

Marysya12 [62]

Answer:

x = 14

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (14 $\sqrt{2}$ )²

2x² = 392 ( divide both sides by 2 )

x² = 196 ( take the square root of both sides )

x = $\sqrt{196}$ = 14

Thus the congruent legs are 14 cm

Pls help, Thx! Solve using the substitution method.<br> y = 2x - 4<br> 6x - 3y = 12

Kay [80]

Your answer would be 0 and -4. When you plug in 2x - 4 in for the y of the second equation and solve, you get x = 0 and y = -4.

$\bf \cfrac{x^3+5x^2+3x-10}{x+4}\impliedby x+4=0\implies x=\stackrel{our~divisor}{-4}\\\\
-------------------------------\\\\
\begin{array}{r|rrrrrrr}
-4&&1&5&3&-10\\
&&&-4&-4&4\\
--&&--&--&--&--\\
&&1&1&-1&\boxed{-6}&\leftarrow remainder
\end{array}
\\\\\\
1x^2+1x^1-1+\frac{-6}{x+4}\implies x^2+x-1+\frac{-6}{x+4}$
