Answer:
30 inches
Step-by-step explanation:
Assuming the lengths are measured when B lies between A and C on a line, the segment addition theorem applies:
AC = AB +BC
42 = AB + 12 . . . . . fill in the given numbers
30 = AB . . . . . . . . . subtract 12
The length of AB is 30 inches.
An estimate helps you place the decimal point when multiplying because if you find out how many decimals there are and once you are done doing you estimated multiplication you put two decimal points after that.
Hope I helped some what and didn't make you confused.
Answer
Area = 35cm^2
Explanation
Area of a parallelogram = b•h
In this question, we are given the values:
H = 5cm
B = 7cm
Therefore, the area is 5 x 7
= 35 cm^2

Letting n approach infinity results in the undefined "infinity over infinity."
Differentiate numerator and denominator separately, obtaining
1/n
(limit as n approaches infinity of) ------------- = 0. Series is convergent.
