The expression x3 + 16x2 + 68x + 80 represents the volume of a flower box in cubic inches. The expression x + 4 represents the depth of the box. Assume
that the length is greater than the height and that linear expressions with
integer coefficients represent both.
a. What are the other dimensions of the flower box?
b. If x= 3, what are the dimensions of the flower box?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
