First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).
We do what's in the parenthesis first.
9+9(2+4)÷3-2.
2+4=6.
Now our problem looks like this;
9+9(6)÷3-2
OR
9+9×6÷3-2.
Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.
Next, we do all the multiplication in our problem.
9+9×6÷3-2.
9×6=54.
Now our problem looks like this;
9+54÷3-2.
Next, we do the division.
9+54÷3-2
54÷3=18.
Now our problem looks like this;
9+18-2.
Next, we do the addition.
9+18-2
9+18=27
Now it looks like this;
27-2.
Finally, we subtract.
27-2=25.
Your final answer is 25!
Have a nice day! :)
Answer:
None of the above.
Step-by-step explanation:
All of these are functions. For each input of x, there is only one output of y. Therefore, they are all functions.

The answer for the following part is
<h3>What is Volume?</h3>
Surface area is the amount of space covering the outside of a three-dimensional shape.
Surface Area of Cone,
= πrl + πr²
=3.14*8*15.77 + 3.14* 8*8
= 597.61804 mm²
Surface Area of triangular pyramid,
= apothem * slant height * length
= 73.6 m²
Surface Area pentagonal pyramid
= B + LA
= 247.75 + 5 ( 1/2*12*19.5)
= 247.75 + 5 ( 117)
= 832.75 in²
Surface area of square pyramid
= P*l /2
= 2400 ft²
