Answer:
Let's simplify step-by-step.
(−a)(−4 − 5a) − 3a(2 + a)
Distribute:
= (−a)(−4) + (−a)(−5a) + −3a^2 + −6a
= 4a + 5a^2 + −3a^2 + −6a
Combine Like Terms:
= 4a+5a^2 + −3a^2+ −6a
= (5a2+ −3a^2) + (4a + −6a)
= 2a2 + −2a
Final Answer:
= 2a^2−2a!
Answer:
0.5km/h
Step-by-step explanation:
Assume lake has no current.
.
V=distance / time
V=39km / 3h
V=13km/h
In water Assume boat used same power travelling
V=35km / 2h
V= 12.5km/h
Current is the difference 0.5km/h
Answer:
What I usually do is find out the actual answer then round it. Make sure to write down that maybe you used mental math or a process of steps you have learned. Hope this was a bit helpful.
FIRST IS 11/25 then 45% and 0.46
Hello!
What you would want to do first is to multiply 8 by 16. If your rate is $8 an hour and you work 16 hours, you'll need to multiply 8 by 16. Once you've done that you should now have $128. Now if you stick with your payment rate for 11 weeks, then you'll need to multiply 128 by 11. After you've done that you will have your answer of $1408
I hope this helps!
