<span>It is easier to multiply. For example: 63 multiply by 7
</span><span>63 x 7 = (60+3) x 7 = 60 x 7 + 3 x 7 = 420 + 21 = 441
</span>
Another example : <span>25 x 73
</span>25 x 73 = (20+5) x (70+3) = 20 x 70 + 20x3 + 5x70 + 5x3
= 1400 + 60 + 350 + 15 = 1875
The distance would be 17.
all you need to do is plug the points into the distance formula.
Answer:
207,50
Step-by-step explanation:
1% = 2,5
2,5x25 = 62,5 250 - 62,5 = 187,5
2,5x8 = 20
187,5+20= 207,50
This should be the correct answer. I recommend Desmos.
