Solve for z.

–2.9 + 4.2z = –14.73 − 12.74 + 0.3z

z =

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

If abcde is reflected over the x-axis and then translated 3 units left, what are the new coordinates d?

Factor the polynomial, if possible. if the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75
