Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
Answer:
e. 5.0329 g/mL
Step-by-step explanation:
Density is defined as mass divided by volume of an object. The volume displaced is:
#Density is then calculated as:
#Correct significant figures should correspond to the highest given in the question.
Hence the density of the metal is 5.0329g/mL
