Answer:
Step-by-step explanation:
The denominators are same. Add fractions.
Factor out the expression in the numerator.
Cancel common terms.
-3
-3k / ( k-2) + 6 / ( k-2)
since the denominators are the same we can add the numerators
(-3k+6) / ( k-2)
Factor out -3
-3 ( k-2)/ ( k-2)
Cancel like terms
f( x ) = - 1/3 x + 5
.................................
least to greatest
-4.5
-4
-3 1/2
2.5
PQ = 16
PQ + QR = PR
(x + 6) + (3x) = 5x -4
4x + 6 = 5x -4
x = 10
10 + 6 = 16
