Total of (99 - 10) + 1 = 90 numbers
probability is 1/90
Step-by-step explanation:
This quadratic does not have rational roots:
x2+9x+2
=(x+(sqrt(73)+9)/2) (x-(sqrt(73)-9)/2)
Unless there is a typo.
Just a guess, if the question had been x^2+9x+20, then
x^2+9x+20
x^2+5x + 4x+20
=x(x+5) + 4(x+5)
=(x+4)(x+5)
Answer:
930
Step-by-step explanation:
1) Once upon a time there was a bored kid in class who invented a super cool formula
This formula goes like this:
n(n+1)
where n= the sum of the first n numbers in a series
so
30(30+1)=30(31)=930
930
The answer will be I believe is 25.16. you will dived 372 by 12 and what you get from that you will dived 780 by the answer.
The answer would be B.About 25 inches! :)
