Step-by-step explanation:
In order to answer this problem, we need to add together similar terms. It is better to rearrange the terms so as to eliminate confusion and minimize the error in the calculation. There are three terms in the given equations, these are
a^3b
a^2b^2
and constant
therefore the answer is
-5a^3b - a^2b^2 +4
I think it’s the third one, i could be wrong
Answer is b my friend hope it helps if ya need me to explain I can for u:3
Answer:
Step-by-step explanation:
Use the factor-label method you learned in chemistry (also known as dimensional analysis), keeping in mind 2 things:
the label you want needs to be on the top of the equivalent ratio, and
that there are 5280 feet in 1 mile. Having said that:
![7feet*\frac{1mile}{5280 feet}=](https://tex.z-dn.net/?f=7feet%2A%5Cfrac%7B1mile%7D%7B5280%20feet%7D%3D)
The math tells us to divide 7 by 5280. That means that
7 feet = .0013257576 miles, to however many decimal places you need. That 7575 is repeating, btw.
