Rect expressions. ssions are equivalent to 3x + 2(x - 1) - 4?​

Step-by-step explanation:

Simplify the expression.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
