Evaluate, given x = 9 and y = 8: x2 + y2 - 1/ 1/2

X=9
Y=8
9•2+8•2-1 1/2
18+16-1 1/2
34-1 1/2
32 1/2
Answer is 32 1/2

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
