Jill is factoring the expression her work is shown below. factors of 1, 13, x, y factors of 52y: 1, 2, 26, 52, y gcf: y factored expression: which best describes the accuracy of jill’s solution? jill’s solution is accurate. jill omitted a factor pair, which affected the gcf and factored expression. jill made an error when determining the gcf from her list of factors. jill made an error when writing the factored expression.

It doesn't seem like we're given quite the whole problem here but I think we're given enough to do it.

Presumably Jill's problem is GCF(13xy, 52y) which equals 13y not y.

52=4(13) so Jill omitted a factor pair, which affected the GCF and factored expression

answer: the common difference is -0.10

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
