Algebra.Com's Answer #154762 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! .Is it ax^2+bx+c=0? If so, is 1(x)2+4(x)-77=0? How do I get the number representing how many apples are on each tray? Thank you,\r \n" ); document.write( "\n" ); document.write( "OK!!! GOOD WORK!!!! ALL YOU NEEDED TO DO WAS SOLVE THE QUADRATIC BUT IT MAY WORK BETTER IF YOU SET THE PROBLEM UP SIMILAR TO THE MANNER THAT I DID BELOW. IN OTHER WORDS, SPECIFY WHAT THE UNKNOWNS REPRESENT\r \n" ); document.write( "\n" ); document.write( "Let x=number of apples that are in each row on each tray \n" ); document.write( "Then total number of apples on each tray=x^2 (Since square trays are specified, the number of apples in the rows are the same as the number of apples in the columns) \n" ); document.write( "Now the man drops x^2 apples \n" ); document.write( "and the girl drops 4x apples \n" ); document.write( "So the total number of apples on the floor is \n" ); document.write( "x^2+4x and we are told that this equals 77 \n" ); document.write( "Thus, our equation to solve is: \n" ); document.write( "x^2+4x=77 or \n" ); document.write( "x^2+4x-77=0------quadratic in standard form and it can be factored: \n" ); document.write( "(x+11)(x-7)=0 \n" ); document.write( "x=-11---------------no good!!! can't have negative apples \n" ); document.write( "x=7----------------number of apples that are in each row on each tray \n" ); document.write( "x^2=49-------------number of apples on each tray\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "man drops 49 \n" ); document.write( "girl drops 7*4=28 \n" ); document.write( "49+28=77 \n" ); document.write( "77=77\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
