Pls help me with this and no links Simplify the following expressions containing factorials.
1. 5!x4!/3!
2. 5!(4-2)!/0!
3. 7!/3!x2!
4. 6!(5!-3!)/3!x4!

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
