I think the answer is 42

Step-by-step explanation:

So, with all of that, the equation will now be = 5^2 + (2 * 8) / 2 + (3 * 3)

So next, you can use PEMDAS. After that, u should get ur answer of 42.

Work:

5^2 + (2 * 8) / 2 + (3 * 3)

5^2 + 16 / 2 + 9

25 + 16 / 2 + 9

25 + 8 + 9

25 + 17

= 42

Tresset [83]

Answer:

278 square centimeters

Step-by-step explanation:

You need to use the Pythagorean Theorm. If you're pyramid is a perfect square, then to the middle the length is 5. Because 10/2 is 5. You then use the Pythagorean Theorm (a^2 + b^2 =c^2) to find the side length of the traingle. When you square the hypotenuse and subtract the bottom leg sqaured, you are left with 3.46274054 after square rooting it. (c^2-a^2=b^2) Plug these into the equation for a right, rectangluar pyramid. You then get 277.9, rounded, is 278.

Hope this helps!
