The artistic crop isn't helpful; it cuts off some vertex names.
The circumcenter H is the meet of the perpendicular bisectors of the sides, helpfully drawn. We have right triangle ELH, right angle L, so
EH² = HL² + EL²
EL = √(EH² - HL²) = √(5.06²-2.74²) ≈ 4.2539393507665339
Since HL is a perpendicular bisector of EF, we get congruent segments FL=EL.

8! is 40,320
Step-by-step explanation:
- Step 1: Find 8! (8 factorial).
Factorial of 8 is the product of 8 and all the integers below 8.
⇒ 8! = 8×7×6×5×4×3×2×1
= 40,320
For this case we must find the value of "x" of the following equation:
So:
We add 9 to both sides of the equation:
We apply square root on both sides of the equation to eliminate the exponent on the left side:
Thus, the solutions are:
ANswer:
Opcion C
This is an arithmetic sequence because the difference
between the terms in the sequence remain constant.
In other words, we subtract 9 from one term to get the next.
So we start off with the explicit formula, shown below in yellow.
"n" will be the number of terms in the sequence,
a1 will be the first term in the sequence,
and d will be the common difference.
Now substitute these in like I have below.
You will get -425 as an answer.
