Answer:
Ok so im not the best at explaining but its worth a shot
C)25
Step-by-step explanation:
we already know that the formula to find area is
A=l*w
and that every square is 1 square unit.
So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part so you multiply 8*2 to get 16.
In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.
In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.
Add 16+6+3 together because that is the combined area of the 3 parts and we get 25
Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments
I'll try to help you round these numbers
37 rounded to Tens will be 40
because 7 is bigger than 3 so the 7 will change the 3 to a 4 and the 7 will be a 0.
29 rounded to Tens will be 30
because the 9 is bigger than 2 so it will change the 2 to a 3 and the 9 will be a 0. Just like 37 rounded into a 40.
669 rounded to Hundreds will be 700
Its 700 because the 9 is bigger and it will change the 6 beside it to a 10 which means that the 9 will be a 0. The 6 that turned to a 10 will turned will be a 0 because your carry the 1 to the other 6 which would turn to a 7 and the two numbers behind 7 will be 0's which makes that be 700.
9,492 rounded to Thousands will be 9,000
Ok this is 9,000 because the 4 is smaller than 9 which the 9 will become the bigger person and turn all the little numbers thats behind it to 0's and even that 9 between the 4 and the 2. So thats why its 9,000.
Hope this helps!

We can get the least number by taking LCM of 24 and 16.
We list each of the numbers as prime factors and take the mutiplication of each unique prime factor that occurs the greatest number of times.
24 = 2 * 2 * 2 * 3
16 = 2 * 2 * 2 * 2
So,
2 occurs four times
3 occurs 1 times
LCM of 24 and 16 is:
2 * 2 * 2 * 2 * 3 = 48
Least number of cheese and cracker appetizer = 48
4b.
Sleeves are sold in 24.
So, to get 48, she would need to buy:
48/24 = 2 sleeves
4c.
Cheese slices comes in packages of 16. So she needs to buy:
48/16 = 3 packages of cheese
The answer is 8
:)
16^3/2 is 64
And 64^1/2 is 8
