Answer:
A triangle with sides measuring 20, 21, and 29
Step-by-step explanation:
6 because if it is .5 and up it rounds to the next whole number
Answer:
Step-by-step explanation:
It is a function because each Input value maps to one output value.
Since we will be completing the square we need to isolate the x
y-5 = 2x^2 -4x
now we the coefficient of the x^2 to equal 1 so we take 2 as common factor
y-5 = 2(x^2 -2x)
now we'll make it perfect square by adding 2 to both sides
y-5+2=2(x^2-2x+1)
now simplify and convert the right side to squared expression
y-3 = 2(x-1)^2
now isolate the y
y = 2(x-1)^2 +3 that's it
