In making a lawn in the garden, the cost of fencing is $20 per metre and the cost of flower -planting is $50 per metre square. Let x be the length of a side of the lawn in metres.
(a) If $ F is the cost of constructing the fence, find a formula connecting F and r.
(b) If $ Pis the cost of flower-planting, find a formula connecting P and x.
(C)
If $ T is the total cost of making the lawn, find a formula connecting T and x.​

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
