Answer:
5x2y2 is the GCF common factor of the following terms.
A= 3,2
B= -1,-1
C= 3,4
D= 1,4
Answer: -3n+31
Step-by-step explanation:
1. 28-55=3
25-22=3
22-19=3
19-16=3
This means that n = -3 as we are subtracting
2. We then do the opposite, we take the first number and we add 3 instead of taking it away we get 31.
That is how you get your answer
-3n+31
Because the angles are supplementary, they add to 180 degrees.
I solved this by dividing

which gives me 30 degrees.
multiply 30 by 5 gives you 150.
and 30 + 150 = 180
Answer: (50 + 2) + 20 +4
Step-by-step explanation: you can split each number into two parts that equal that number, like 52 could be 31 +21
