a piece of wire 7 by 8 long broke into two pieces one piece was 1 by 4 metre long How long is the Other piece

Identify the translation rule on a coordinate plane that verifies that square a(-4, 3), b(-4, 8), c(-9, 3), d(-9, 8) and square a'(-3, 2), b'(-3, 7), c'(-8, 2), d'(-8, 7) are congruent.

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

Two lines that do not intersect are skew. always sometimes or never
