The error is that -2 times -5 is 10 not -10. Then carry on from there because that error meant the rest is wrong as well.
The profit is going to be the total amount made, so you are going to subtract $350 - $45 = $305. $305. I hope this helps!
The factors are
(m-6)(m+6)
Explanation:
Group the first two terms and factor out the common factor:
i.e m(m-6)
Repeat the procedure for terms 3 and 4.
6(m-6)
Regrouping:
m(m-6)+6(m-6)
On factoring out (m-6), we get:
(m-6)(m+6)
We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
