GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
the GCF is 6y
2 times 3 times 3 times x times y = 18xy
18xy is the GCF of 72x2y and 18xy
The GCF is 6xy. The LCM is 72xy2
The GCF is 13x
We are missing an important sign (+/-) I shall assume 9x2 - 18xy + 9y2 9(x-y)(x-y)
lcm(8x, 18xy) = 72xy 8x = 23 x x 18xy = 2 x 32 x x x y lcm = 23 x 32 x x x y= 72xy
63
GCF = 9To find the LCM, find the prime factorization of each number9y = 3 * 3 * y18x = 2 * 3 * 3 * xLCM = 2 * 3 * 3 * x * y = 18xy
That equation represents only one line. y - 11 = 13x - 7 y = 13x + 4 The slope is 13.
That equation represents only one line. y - 11 = -13x - 7 y = -13x + 4 The slope is -13.
