Two sets of equatic expressions are shown below in various forms: line 1: x2 + 3x + 2 (x + 1)(x + 2) (x + 1.5)2 − 0.25 line 2: x2 + 5x + 6 (x + 2)(x + 3) (x + 2.5)2 + 6.25 which line contains three equivalent expressions? a. line 1 only c. both line 1 and line 2 d. neither line 1 nor line 2

What is answer b, or did you just mess up the lettering?

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
