The side lengths of △JKL are 60 cm, 80 cm, and 100 cm. Which formula can be used to show that △JKL is a right triangle?

60^2+1002=80260 squared plus 100 squared is equal to 80 squared

60^2+802=100260 squared plus 80 squared is equal to 100 squared

60^2−802=100260 squared minus 80 squared is equal to 100 squared

80^2−602=100280 squared minus 60 squared is equal to 100 squared

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
