Algebra.Com's Answer #122095 by NerdvanaGirl(8) ![]() You can put this solution on YOUR website! For 3(p+1)^2=81 \n" ); document.write( "I would start by dividing both sides by 3 \n" ); document.write( "Therefore (p+1)^2=81/3 or (p+1)^2 = 27 \n" ); document.write( "I would then take the square root of each side \n" ); document.write( "p+1 = radical 27 \n" ); document.write( "Then subtract 1 \n" ); document.write( "p=(radical 27) - 1 or p = -1 + (radical 27) or punch in radical 27 into a calculator and then subtract 1, which is 5.1961524 - 1 = approximately 4.196\r \n" ); document.write( "\n" ); document.write( "For 5y^2+4=14 \n" ); document.write( "I would first subtract 4 \n" ); document.write( "so 5y^2=10 \n" ); document.write( "Then divide by 5 \n" ); document.write( "y^2=2 \n" ); document.write( "Take the square root \n" ); document.write( "y= radical 2 or y= approximately 1.41421 \n" ); document.write( " |
