Answer:
Well, for one thing I can't read the image--it's too small!
But I know these problems well. If I am correct, this is a spinner probability problem.
Your spinner appears to have 5 sectors, all equal in area, therefore making their probability equal.
So each of those has a prob of 1/5 in the scheme of things.
To find the combonational probability below, multiply the prob of each outcome together to find each.
Have a great day, and feel free to comment with questions!

Answer:
B
Step-by-step explanation:
B
the vertex is (-5,-2) which eliminates A and C. D says that the x intercepts are both positive which is obviously incorrect making B the correct answer
Answer: C
Step-by-step explanation:
Okay first set a comparison since the two triangles are similar
x-1/20=x-1+27/3x+8
x-1/20 = x+26/3x+8
cross multiply
20x+520=3x^2+8x-3x-8
3x^2-15x-528=0
3(x^2-5x-176)=0
im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid
x=16, x=-11
it has to be positive so x=16
