Answer: a.) 3
Step-by-step explanation: An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
Step-by-step explanation:
this is an arithmetic sequence :
a1 = 1
an = an-1 + 2 = a1 + (n-1)×2
the sum of n terms of an arithmetic sequence is
S = n×(a1 + an)/2
n = 5000
an = a1 + 4999×2 = 9999
S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000

(please give me brainliest)
OK. Let's build this thing brick by brick,
one step at a time:
The number. . . . . . . . . . . . . . . . . . . . . . . N
==> Three times the number . . . . . . . . 3N
6 times the number. . . . . . . . . . . . . . . . 6N
==> 28 more than 6 times the number . 6N + 28
You said the three times the number is the same
as 28 more than 6 times the number.
So I can write
3N = 6N + 28
That's the equation.
Subtract 3N from each side: 0 = 3N + 28
Now subtract 28 from each side: -28 = 3N
Now divide each side by 3 : N = - 28/3 .
That number is kind of weird, but it's the ONLY number
that behaves according to the description in the question.
Three times the number . . . . . -28
6 times the number . . . . . . . . . -56
-28 is 28 more than -56. yay!
