Answer:
1
Step-by-step explanation:
Answer: multiply and estimate
Step-by-step explanation:
If X = 1 rhen it would be 3x5 so it would be 15 and for the other side X would have to be -3
88= 2l + 2w
l=3w
88=2(3w)+2w
88= 6w+2w
88=8w
w=11
l=3(11)
l=33
width= 11
length= 33
Answer:
B. 
Step-by-step explanation:
We have,
The first term of the series,
.
The common difference is given by,
i.e.
.
Since, the given series is an infinite series, then,
Sum of an infinite series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
Thus, the sum of the series is
.
