Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
3.5 because you take 7 and divide by 2 since you have to multiply you base times width to get area I think I might be wrong
16 is the answer. All 3 numbers can be divided by 16 at most. It can’t be 16a because 48b does not have a. It can’t be 16b because 32a does not have b.
