Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can yo

u find her mistake? 1 2 (4k + 8) = 10 1. 2k + 16 = 10 2. 2k = −6 3. k = −3 What was Callie’s mistake? Callie should have added 10 to both sides in step 2. In step 1, when Callie distributed the One-half to the 8, she multiplied incorrectly. Callie divided by 2 instead of multiplying by 2 in step 3. Callie should have added 16 to both sides in step 2.

lidiya [134]
We have the <span> Trigonometric Identities : </span>secx = 1/cosx; (sinx)^2 + (cosx)^2 = 1;
Then, 1 / (1-secx) = 1 / ( 1 - 1/cosx) = 1 / [(cosx - 1)/cosx] = cosx /
(cosx - 1 ) ;
Similar, 1 / (1+secx) = cosx / (1 + cosx) ;
 cosx / (cosx - 1)  +  cosx / (1 + cosx) = [cosx(1 + cosx) + cosx (cosx - 1)] / [ (cosx - 1)(cox + 1)] =[cosx( 1 + cosx + cosx - 1 )] / [ (cosx - 1)(cox + 1)] =  2(cosx)^2 / [(cosx)^2 - (sinx)^2] = <span> 2(cosx)^2 / (-1) = - 2(cosx)^2;
