Answer:
Prime
Step-by-step explanation:
This expression is actually impossible to factor. To get rid of the middle term, you would need two equal and opposite x values, such as in (x+4y)(x-4y). However, in that case, the expanded expression would be x^2-16y^2, not plus. If you go for the first option, then you are left with a middle term, such as 8xy. Therefore, this expression is prime. Hope this helps!

Answer:
169 
Step-by-step explanation:
The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.
(7) * (5) = (35)
(9) * (5) = (45)
(7) * (5) = (35)
(
) * (6) * (9) = (27)
(
) * (6) * (9) = (27)
Add up all of the values:
(35) + (45) + (35) + (27) + (27) = 169
