Simplify<br> 21x^6 y^5<br> 14x^2y^9
PIT_PIT [208]

Answer:

\frac{3x^{4} }{2y^{4} }

Step-by-step explanation:

Factor out 7 from top and bottom :

\frac{7(3x^6y^5)}{7(2x^2y^9)}

Divide top and bottom by 7 :

\frac{3x^6y^5}{2x^2y^9}

Simplify :  

\frac{x^6}{x^4}=x^{2}

Simplify :

\frac{y^5}{y^9} = y^{-4}  = \frac{1}{y^{4} }

Collect everything together :

\frac{3x^{4} }{2y^{4} }

Hope this helped and have a good day

Find measure jk <br> Answers are 52, 128, 154 &amp; 180
Mamont248 [21]

Answer:

b. 128°

Step-by-step explanation:

arc LJ = 2 (26) = 52°

arc KL = 180° (half circle)

so

arc JK = 360° - (arc LJ + arc KL)

arc JK = 360° - 232°

arc JK = 128°

Answer

b. 128°
