Answer:
6x +3w
Step-by-step explanation:
3(2x + w)
Distribute
3*2x +3*w
6x +3w
You just find the numbers that you can multiply to get -28
W = L - 5
546 = L × ( L - 5 )
546 = L^2 - 5L
L^2 - 5L - 546 = 0
( L - 26 ) ( L + 21 ) = 0
L = 26 , L = - 21
L = 26
length cannot be in negative , so ignore the negative answer
