Answer: 136 units squared
Step-by-step explanation:
I will assume this is a rectangular prism since it isn't specified.
The surface area of a rectangular prism: SA = 2(lw+lh+wh).
Plugging in your dimensions: SA = 2(7*2 + 7*6 + 2*6) = 2(14+42+12) = 2(68) = 136 units squared.
As already described above, the prime polynomial is that which can no longer be factored to yield a much simpler terms. From the given choices, that which cannot be factored is letter C.
2/7 because its a part to whole ratio.
I think x is 20 I’m not sure tho since it would come out as -10 instead of positive
