Answer:

(h+k)(2) = 5

(h-k)(3) = 9

3h(2) + 2k(3) = 17

Step-by-step explanation:

  • (h+k)(2)
  • h(2) + k(2) = ((2)²+1) + ((2)-2) = 5 + 0 = 5

  • (h-k)(3)
  • h(3) - k(3) = ((3)²+1)-((3)-2) = 10 - 1 = 9

  • 3h(2) + 2k(3)
  • 3(5) + 2(1) = 15 + 2= 17

Problem 16)

12.446 cm^2

Step-by-step explanation:

Problem 15)

Gala.

17.28 + 15.12 + 8.51 = 40.91

Problem 16)

WILL MARK THE BRAINLEIST Find the surface of the rectangle prism ,show all of your work
trapecia [35]
The answer is 108 as your surface area.

Work:
To find surface area, you find the area of each side and add it all together. For the bottom and the top sides, it’s 6 x 3 which equals to 18. 18 + 18 = 36. Then, 3 x 4 = 12. 12 + 12 = 24. 6 x 4 = 24. 24 + 24 = 48. Then, you add it all together which equals to 108. If what I did doesn’t makes sense, I’ll explain it more detailed here.

So, I found the area of the bottom side and multiplied it by 2 to represent the top and bottom sides. Then, I did the same thing for the other sides if that makes sense. I’m really sorry if I’m not explaining it well. I’m better at doing the work in my head and not on paper or explaining it to other people.

Anyway, hope this helps!
