Total surface area of first box = 2(8 * 6.25) + 2(8 * 10.5) + 2(6.25 * 10.5) = 2(50) + 2(84) + 2(65.625) = 100 + 168 + 131.25 = 399.25 sq. ins

Total surface area of second box = 2(9 * 5.5) + 2(9 * 11.75) + 2(5.5 * 11.75) = 2(49.5) + 2(105.75) + 2(64.625) = 99 + 211.5 + 129.25 = 439.75 sq. ins

Hence, the second box requires more material to make.

Answer:

B. 30

Step-by-step explanation:

A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.

A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Hope this helps

Why is it important for the leading coefficient<br> to be nonzero?
kipiarov [429]

Answer:

Because if it is zero, then it is multiplied the variable and it will be zero.  For example if I had 0x(squared) + x, it would just be x because zero times any number is zero.  Looking at the problem, I would assume it was quadratic because it had x squared, but it isn't because there are 0 x squared values.
