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.
5.231.281 : 70.323 = 74,3 people per square mile
or 74 people per square mile
0.75 or 3/4 that’s your answer as a decimal and fraction :)
Answer:
8x + 70x²
Step-by-step explanation:
this would be the equation chosen wisely
I really don't know what you mean, but to find the percent, multiply x and y and then divide your answer by 100, or move your decimal place to the left twice. hope that helped :)
