Answer:
1,038 in2
Step-by-step explanation:
In a regular hexagon, the radius and side length are equal in length... That makes the answer 1038 in.2 correct?
Lila did it correctly. The answer is 324
Following PEMDAS, we first focus on the parenthesis. So we simplify 9-3 to get 6
So we go from
18*4^2+(9-3)^2
to
18*4^2+6^2
The next step is applying exponents. In this case, squaring the terms, so we go from
18*4^2+6^2
to
18*16+36
Next is multiplying
18*16+36
turns into
288+36
Finally, add up 288 and 36 to get 288+36 = 324
That confirms that Lila is correct
----------------------
The error that Rob made is that he computed 18*4^2+9^2-3^2 but it is NOT correct. Saying (x-y)^2 = x^2-y^2 isn't a true equation for all x and y. Again you have to simplify what is in the parenthesis first, and then you can square it. Or you must use the FOIL rule to expand out (9-3)^2
12 tables seat 4 people = 48 seats
28 tables seat 2 people= 56
therefore there are 104 seats
The expression:
3 (x - 2)
indicates that the number 3 before the parenthesis is multiplying the expression inside the parenthesis.
Then in order to do such we use what is called the distributive property which tells us to "distrubute" suche multiplication among the two term that are in the parenthesis:
3 x - 3 * 2
3 x - 6
Which is the first option in your answer list.
