Answer:
x² + 8x + 12
Step-by-step explanation:
see
the length of the entire rectangle = x + 6
breadth of the entire rectangle = x + 2
area of a rectangle = length × breadth
= (x + 6)(x + 2)
= x² + 8x + 12
which is the required polynomial in standard form
You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.
30
It’s a word problem for LCM
3 x 10 which will give you the lowest common multiple (LCM) also giving you the lowest number of clusters

Answer: 7</h3>
=======================================================
Explanation:
x = number of people
33.25x = cost of the tickets only, without parking
33.25x+14 = add on the cost of parking
33.25x+14 = 246.75
To solve this equation we'll do these two steps in the order mentioned
- Subtract 14 from both sides. This is to undo the +14
- Divide both sides by 33.25 to undo the multiplication.
The idea is we follow PEMDAS in reverse undoing everything so we can isolate x.
So,
33.25x+14 = 246.75
33.25x = 246.75-14 ............. step 1 mentioned earlier
33.25x = 232.75
x = 232.75/(33.25) ................ step 2 mentioned earlier
x = 7 is the final answer
---------------
Check:
7 people go to the amusement park
At $33.25 per person, that amounts to 7*33.25 = 232.75 dollars so far.
Then add the cost of parking to get 232.75+14 = 246.75 to match the total amount spent stated in the instructions. The answer has been confirmed.
Notes:
- This assumes they all went in the same vehicle.
- They'll need to bring more money if they want things like food, drinks, souvenirs, playing carnival games to win prizes, etc.
