Answer:
it's x= 1±sqrt(47)
Step-by-step explanation:
50+5x=total profit. To get 10% of 50 you would multiply .1x50= 5. X would be the amount of days past so 10th day = $100 total but $50 profit and 30th day = $200 total but $150 profit
i am not 100% sure but...
(4x+3)=47
<u> - 3 - 3 </u>
4x=44
44/4= 11
so x = 11
That would be (k^2 y^2), or simply (ky)^2 .
the answer is gonna be a. 5m+40
