Answer: 10

Step-by-step explanation:

Start with parenthesis, (-8 + 4), which equals -4.

Then, move to multiplication, -3 x (-4), which equals 12.

Finally, addition, -2 + 12, which equals 10, your final answer.

Someone please help and show work!! I will also mark brainliest. I’ll appreciate it.
Eduardwww [97]

Answer:

1. 53

2. 20

3. 37

4. 29

Step-by-step explanation:

Since your trying to find the hypotenuse you equation is...

1. 28^2 + 45^2 = C^2

    784 + 2025 = C^2

      Square Root 2809= C^2

    C=53

So after you square root 2809 you get 53.

2. 12^2 + 16^2 = C^2

     144 + 256 = C^2

      Square Root 400 = C^2

    C=20

So after you square root 400 you get 40.

3.  12^2 + 35^2 = C^2

    144 + 1225 = C^2

    Square Root 1369 = C^2

   C=37

So after you square root 1359 you get 37.

4. 20^2 + 21^2 = C^2

   400 + 441 = C^2

  Square root 841 = C^2

  C=20

So after you square root 841 you get 29.
