Answer:
5
Step-by-step explanation:
18= +5+x
x=3
If you do 3•5, you get 15.
Then do 3+15, you get 18.
okay well usually what I would tell you would be to use the ABC method. you would multiply A (2) by C (6) to get twelve. so you need two numbers that multiply to twelve and add to -4 (the B value). but there are no numbers that fit this description so you have to use the GCF method instead
for this method you must find the GCF for all three numbers which in this case is 2. 2(x^2-2x+3) all these numbers are now prime so this is the factored form
True because all of the numbers here divide and multiply back in to the original number 12,570.
