Which of the following is equal to the rational expression when x 4 or -9? (x - 4)(x +11)
(x +9)(x-4)

A.
X - 4
x + 11

B.
X+ 11
X +9

c.
X+ 11
X-4

D.
X-4
X + 9

The answers would be fractions but I wasn’t sure how to write that out.

Use the elimination method to find the solution to the system of equations. 2x - 3y = -9 -x + 3y = 6

Which expression is equivalent to (4x^3*y^5)(3x^5*y)^2 \a) 24x^13*y^7b) 36x^13*y^7c) 36x^28*y^7d) 144x^16*y^12
