Answer:
I got 358,800
Step-by-step explanation:
First you can choose from 26 letters, then from 25 (because you can't use the same letter) then from 24, and then from 23. You multiply 26 * 25 * 24 * 23 and you get your answer.
I think :)
You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
32. 16 through opposite vertices and 16 through the centres of opposite sides
