I feel really bad for you. This looks like a death problem
It's an isosceles triangle so both sides are the same. The missing side is 30
The answer is C it’s vertex is at (2,4) because a quadratic formula is suppose to look like y= a ( x - h )^2 + k and the vertex is (h,k) when you look back at Your question h=-2 and but Bc of the formula then it’ll be h=2 and then k=4 and that’s how you get the vertex from a quadratic formula. Hope this helps :)
Answer:
320
Step-by-step explanation:
5x4=20, 20x4=80, so that means the sequence is just multiplying by 4. 80x4=320, which is your answer.
