7000/500 = 14
The diameter is 14mm in the drawing.
Step-by-step explanation:
5x³ - 45x
5x(x² - 9)
Or 5x(x-3)(x+3)
Perimeter is the distance around a shape. The way you find it is by adding the lengths of every side.
In this case, it is 3+4+5=12 cm

is equivalent to <span>

That is in the form </span><span>

which is point slope form
In this case,
m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
