The answer is D.
1 sq ft = 1 ft x 1 ft
= 12 in x 12 in
1 sq ft = 144 sq in
5 sq ft = 144 * 5 = 720 sq in.
Check the picture below.
notice the sides, now, on the second triangle, side 6 slants a bit more to fit in 13, on the third triangle, side 6 slants even further to fit 13 in, now, if 6 were to slant completely, it'll make a flat-line with side 5, and there will be a triangle no more.
but even if side 6 would stretch to a flat-line, 5+6 is just 11, whilst side 13 is longer than that, so no dice.
The answer would be J because if the equation was transferred into a positive then it would be 2y and 5x marking 5x on the bottom and 2y vertically.
Hope this helps!!
Right. Your answer is still no because your x-value needs to be positive.
