Determine if 9x2 - 42x + 49 can be the area of a square. if so, what would the value of x have to be if the area of the square is 64 square meters?

18-42x+49=64
42x=67-64
42x=3
x=3/42
x=1/14or0.0712

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.
