Not too sure but I think you’ll have to find out the amount of boys in the class then add that number to the amount of girls to get the answer.
72x^2y and 18xy
GCF = 18xy
This looks like an addition (summation is the technical term) series. Here we need to figure out the difference between each number in the series. The difference between 6.75 and 9.25 is 2.5 (You can subtract the larger number from the smaller number to find out). So, 6.75-2.5=4.25.
So the correct answer in the blank is 4.25, and the rule is +2.5.
Answer:
X= -1 and x=5
Explanation:
Make it equal to zero
X-5=0
Then add five to both sides
X=5
For the other one do the same
X+1=0
Then subtract one on both sides
X=-1
Hope this helps!
