Answer:
When m = 6, 5m - 4 = 26.
Step-by-step explanation:

Substitute:

Multiply:

Subtract:

When m = 6, 5m - 4 = 26.
Are you trying to distribute the b^4 or factor it?
b^4 [(2b^2) + b]
Distributed:
[2(b^6) + (b^5)]
Factored:
b^5 [2b + 1]
So work =time times rate or W=TR
so T=m-k
W=(m-k)R
if you want just m-k then m-k is the answer
