Jim needs to fence in his rectangular backyard. the fence will have 1 long section away from, but parallel to, the length of his house and 2 shorter sides connecting that section to the house.
\n" ); document.write( " the length of Jim's house is (3x+4)yd and the area of the backyard is (9x^2+15x+4)yd squared.
\n" ); document.write( " how many yards of fencing will Jim need?
\n" ); document.write( ":
\n" ); document.write( "Divide that area by the length
\n" ); document.write( "\"%289x%5E2%2B15x%2B4%29%2F%283x%2B4%29\"
\n" ); document.write( "Factor the numerator, then cancel the (3x+4)'s
\n" ); document.write( "\"%28%283x%2B1%29%283x%2B4%29%29%2F%283x%2B4%29\" = 3x+1 is the width
\n" ); document.write( ":
\n" ); document.write( "Only 3 sides need to be fenced
\n" ); document.write( "f = (3x+4) + 2(3x+1)
\n" ); document.write( "f = 3x + 4 + 6x + 2
\n" ); document.write( "f = (9x + 6) yds of fence required\r
