What equation results from completing the square and then factoring? x2 + 4x = 5
A. (x + 2)2 = 3
B. (x + 2)2 = 7
C. (x + 2)2 = 9
D. (x + 2)2 = 1

Estimate the product. round the first factor to the nearest whole number, round the second factor to the nearest ten, and then multiply. 3 8/9 × 96

Which answer goes into the box? (90° clockwise rotation, 90° counter clockwise rotation, translation, or glide reflection)

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.
