A square prism has square sides with area x^2+8x+16 and rectangular sides with area 2x^2+15x+28. What expression represents the surface area of the square prism

10x^2+76x+144

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this scary-looking problem! :P

Remember, the surface area of a square prism is the SUM (+) of the areas of the two square sides AND the four rectangle sides:

    (x^2+8x+16) + (x^2+8x+16) + (2x^2+15x+28) + (2x^2+15x+28) + (2x^x+15x+28) + (2x^2+15x+28)

You may be wondering why we don't just write it as (x^2+8x+16) times itself + (2x^2+15x+28) times 4, but we have to group like terms next, and in order to do that we have to see what what we're left with, as shown below:

    (x^2+x^2+2x^2+2x^2+2x^2+2x^2) + (8x+8x+15x+15x+15x+15x) + (16+16+28+28+28+28)

It may look complicated, I know, but all you have to do now for the final step is combine the like terms, resulting in your answer, 10x^2+76x+144!

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
