Answer: -1410
Step-by-step explanation:
Let's start by subbing in -4 for x

Now we can solve

Since 30 is not a square root you would use the closest square roots √25 and √36 which makes your answer 5 and 6
You divide 8644 by 8 which equals 1080.5, but since you can't have half of one person you approximate it to 1080 or 1081.
It’s 18x because 36 and 54 are both divisible by 18, and 18 can be divisible by 18 (making 1), resulting in 18 being the most common number between the numbers, whereas the ‘x’ is common between all 3 numbers and since the least amount of x is 1, the answer is just x without an exponent
