How do you evaluate #abs2+h+absj# when h=6, j=-4?

Answer 1

#12#

#|2|+h+|j|#

# h=6 and j=-4#

# |2|+6+|-4|#

When taking the absolute value of a number, it is its distance away from #0# or also known as the magnitude of a number.

#2+6+4 = 12#

To evaluate the expression abs(2+h)+abs(j) when h = 6 and j = -4:

abs(2+h) = abs(2+6) = abs(8) = 8 abs(j) = abs(-4) = 4

So, the expression evaluates to 8 + 6 + 4 = 18.
