Algebra.Com's Answer #24644 by Nate(3500) ![]() You can put this solution on YOUR website! Perimeter is twice the length plug twice the width. \n" ); document.write( "P(x)=2(2x-5)+2(3x+9) \n" ); document.write( "P(x)=4x-10+6x+18 \n" ); document.write( "P(x)=10x+8 \n" ); document.write( "P(4)=10(4)+8 \n" ); document.write( "P(4)=48ft. \n" ); document.write( " |
