Hi there! :)
Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:
a² + b² = c²
Use the length and width in the equation:
8² + 3² = c²
64 + 9 = c²
73 = c²
c ≈ 8.54 cm
Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:
(8.54)² + 7² = c²
73 + 49 = c²
122 = c²
√122 = c
c = 11.05 ≈ 11 cm. The correct answer is B.

Step-by-step explanation:
To find the best place to buy the video game, we need to find the price for each store, and see which is least. To do this, find the percents of each and subtract.
To find the percent, simply multiply your original number by a decimal version of the percent
Ex: 160* .4=64
155*.3=46.5
160*.2=32.
Then, subtract the amounts from each price.
160-64=96
155-46.5=108.5
160-32=128
Clearly, store a is the best place to buy the system.
Hope this helps!
Answer: -2
Explanation: The coefficient is the number to the left of the variable.
Another example would be that 10xy has the coefficient 10.
Something like x^2 has coefficient 1 because x^2 = 1x^2.
