Answer:
d
Step-by-step explanation:
5x4 = 20 + 10 = 30 and it cant be a or b because they have too many bills and c doesnt have the right amount of money
Answer:
26
Step-by-step explanation:
Distance between (-2,5) and (-2,1) is 5
Distance between (-2,5) and (6,5) is 8
Distance between (6,5) and (6,1) is 5
Distance between (6,1) and (-2,1) is 8
5+8+5+8=26
Answer:
Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.
240 + 123 > 207 true
240 + 207 > 123 true
123 + 207 > 240 true
A = √(s(s-a)(s-b)(s-c))
s is the semi-perimeter (a + b + c)/2
s = (240 + 123 + 207)/2
s = 285
A = √(285*(285-249)(285-123)(285-207))
A = 12,730 units^2
Step-by-step explanation:
Plug in n = 1 into the nth term formula
a(n) = 4n-1
a(1) = 4*1-1
a(1) = 3
So the first term is 3
The second term will be 7 because we add on 4 each time, as indicated by the slope of 4. This is also known as the common difference.
So the nth term is found by adding 4 to the (n-1)st term, in other words,
a(n) = a(n-1)+4
----------------------------------------------------------------------------
In summary, the answer is
a1=3; an=an-1+4
which is choice B
