Seven cars and vans can be parked in a line in 39 916 800 ways. Find the number of ways in which five cars and x+ 2 vans can be parked in a line.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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.
