Hello here is a solution :
the distance that we would have if we made the line of centimeters the distance would be 1mm, if we did it in decimeter, the distance would be 1cm and then successively.
Answer: 12
Step-by-step explanation:
The circle is 360 degrees in total
360/6 = 60
72/6 = 12
7/8 .. *2 = 15/16
7/8 ...* 5 = 35/40
7/8 ...* 10 = 70/80
You can multiply the numerator and denominator by any number ( must be the same number), to result in an equivalent expression
This is an example of difference of two squares, because 49 is a squared number. Thus, you can write it in the form, (a + b)(a - b).
Thus, [(x - 3) + 7][(x - 3) - 7] = 0
(x + 4)(x - 10) = 0
And the zeros are at: x = -4, 10
