Which of the following polynomials represents a difference of squares? I. x^2- 25
II. 9y^2 – 36
III. 4x^2 +100
IV. 16x^2 - 100

yes. we do proportions in probabilities.

x=30

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
