Using the completing-the-square method, rewrite f(x) = x+ 10x + 7 in vertex fom Ofx) = (x + 5) 18
O f(x) = (x+ 10)2+25
O fx) = (x+ 5)2+7
O f(x) = (x+ 5

i dont know

step-by-step explanation:

is there a picture

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
