Set upa s a proportion
x/60 = 1/9
x = 1/9 * 60
x = 6.67 inches
I am not sure but it is right if your question is right.
10x^3-8x^2-12x^2(x)
10x^3-8x^2-12x^3
-2x^3-8x^2
=-2x^2(x+4)
B.
9 = 3 x 3
21 = 3 x 7
GCF = 3
3 x 3 + 3 x 7 = 9 + 21 = 30
Well I really can't explain but the answer is 0.32 square millimeters...so sorry if this didn't help.
