If one ratio is equivalent to another, that means that you multiply the top and the bottom on one ratio by a constant to get the larger ratio. D does that here for us. We have to multiply 3 by 5 to get to 15, so 16 times 5 better be 80 and it is.
Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = 
x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + x + x - 12 = 107
x -12 = 107
x = 119
x = 51
x = 17
x - 12 = 39
Barry will use the distance formula:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(4 - 3)² + (7 - 1)²]
d = 6.08 units
407 over 5 but it also has to be simplified
2/3 3/4 5/8 7/24 is the answer
