Step-by-step explanation:
denominators showing all working <3
I believe it would be 12/18 so that would be 2/3 and 0.6 in decimal form
4(5x+1)(5x-1) = 0
1. Take out the GCF (in this case, 4)
4(25x^2-1) = 0
2. This can be further factored. Factor the values within the parenthesis
4(5x + 1)(5x -1) = 0
15%
amount error is guess subtract actual amount 198-172 = 26
26/172 = 0.15
0.15 x100 = 15%
