Firstly, foil 10(p+10) and -5(2p+11):
Next, combine like terms:
Next, add 10p on both sides:
Next, subtract 89 on both sides:
Next, divide both sides by 20 and your answer will be
To find your answer, multiply 1.5 by 2.5 since there are 2.5 cm in an inch, and there are 1.5 inches.
You would get 3.75.
Therefore, the paperclip is 3.75 centimeters long.
Hope this helps!
You should use the distributive property next to get rid of the parentheses.
Like terms will have exactly the same variables
so 5a and 2a are like terms
examples :
3b and 4b are like terms
3b and 4a are not like terms
2a^2 + 3a^2 are like terms
2a and 3a^2 are not like terms
3ab and 4ba are also like terms...even though the variables are switched
6b^2a and 6a^2b are not like terms
