Compare the quantity in Column A with the quantity in Column B.
Column A
6z-5 if z=-2
Column B
-6z – 5 if z = 2
Answer-The quantities are equal
Evaluate 2y^2(x+y) when x =8 and y=3
Answer-198
Evaluate 2y^2(x+y) when x =8 and y=3
2(3^2)(8+3)
=2(9)(11)
=198
==============================
Column A
6z-5 if z=-2
6(-2)-5
=-12-5
=-17
Column B
-6z – 5 if z = 2
-6(2)-5
=-17
============================
Column A
The solution of
2(x-3) = 6x
2x-6 = 6x
4x=-6
x=-3/2
Column B
The solution of (note typo assumed)
3x + 2 = 5x + 6
2x=2-6
x=-4/2=-2
