Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side. How much smaller than Ociel's mural is Bill's mural? Explain

Respuesta :

Ocel’s 10x10=100
Bill’s (10 - y) (10 - y)

I don’t know which answer your teacher wants
100 - [(10-y)(10-y)]
100 - (100 -20y + y^2}
20y - y^2
