We can use algebraic operations to rewrite expressions, including polynomial expressions. when we rewrite polynomial expressions, the representations look different but still represent the same expression.

where else have you seen this type of transformation—when something appears different, but its meaning remains the same?

Aplot of land in the shape of a vertical ellipse has a pole at each focus. the foci are 8 feet from the center. if the plot of land is 34 feet across the vertical axis, then it is (a.24 b. 30 c. 32 d. 36) feet across the other axis. the eccentricity of the ellipse traced by the boundary of this plot, rounded to the nearest thousandth, is (a.0.543 b.0.515 c.0.471 d. 0.459)
