-14；-18
Step-by-step explanation:
Answer:
23. 92 points
24. 18.5 years old
Step-by-step explanation:
set up an equation
23. 79=chicago-13
add 13
chicago=79+13=92
24. 15.5=lou-3
loud=15.5+3=18.5
for the given A.P
5,9,13,...
First term (a)=5
common difference (d) = 9-5=4
Let Tn=2012
a +(n-1) d=2012
5 +(n-1) 4=2012
(n-1) 4=2012-5
(n-1)4=2007
n-1=501.75
n=1+501.75
n=502.75 -- - - - - -> which is not possible.
No.of terms can never in fraction.
Hence, 2012 is not a term of given A.P
If you subtract 58 by 14 you will get 44 so thats the answer
Area of triangle = (1/2)*base*height
20.335 = (1/2)*base*8.3
2*20.335 = base*8.3
(2*20.335) / 8.3 = base Use your calculator.
4.9 = base
base = 4.9cm
