Step-by-step explanation: hope this helps :)
When you factor this problem you get:
(3x+5)(x+10)
It A because the two mirror each other so you can simplify them to (3x−5)^2.
I think that person above me should be your answer
Answer:
8 months and $320
Step-by-step explanation:
To find when 30m + 80 = 40m, isolate m.
30m + 80 = 40m
Subtract 40m from both sides.
-10m + 80 = 0
Subtract 80 from both sides.
-10m = -80
Divide both sides by -10
m = 8
To find the cost, substitute 8 as m in one of the equations.
40(8) = 320
