Answer:
a14 = -40,960
Step-by-step explanation:
The sequence has a first term of 5 and a common ratio of -10/5 = -2, so the n-th term is given by ...
an = a1·r^(n-1)
an = 5·(-2)^(n-1)
The 14th term is then ...
a14 = 5·(-2)^(14-1) = -5·2^13 = -5·8192
a14 = -40,960
Answer:
area= x^2+8x+7
Step-by-step explanation:
a=l*w
l=x+7
w=x+1
a=(x+7)(x+1)
a= x^2+8x+7
2miles=20km
20km/4=5km
5km=0,5mile
Runned 0.5 miles in total
Answer:
30 years
Step-by-step explanation:
