Answer:
The length is 72
Step-by-step explanation:
length x width = area
9 x length = 648
length = 72
The answer is b.6 because if you go through and look at each available type of sandwich to make you will get six different selections
So for this, you will be doing two different multiplications: 3 x 4 and √8 x √3.
3 x 4 = 12
√8 x √3 = √24
Now our result is 12√24, however, this can be simplified. Using the product rule of radicals (√ab = √a x √b), our simplification is such:
12√24 = 12√(8 x 3) = 12√(4 x 2 x 3) = 2 x 12√(2 x 3) = 24√6
In short, the answer is 24√6, or the first option.
Based on the ratio of boys/girls We can infer that the only possibility for Ellen's math class would be answer B. 14/21
